-@table @code
-@item all
-Bytecompile all files, build and bytecompile byproduct files like

-of TeXinfo documentation if present.
-@c #### Why do we need this _and_ the binkit target?
+@node Makefile Targets, Local.rules File, Building Packages, Packaging
+@cindex package makefile targets
+@chapter @file{Makefile} targets
+The following targets can be used when running @code{make} to build the
+packages:
+
+@table @samp
+@item mostlyclean
+Removes any documentation files that have been processed by @TeX{}.
+
+@item clean
+Does a @code{mostlyclean}, plus removes generated postscript and dvi
+files. Also removes any generated .elc files, along with the normal
+.elc files in the package and HTML and .info files.
+
+@item distclean
+Use this when preparing a distribution. It kills anything that can be
+rebuilt.
+
+@item extraclean
+Does a @code{distclean} and also removes any backup files (@file{*~})
+and @file{core} files.
+
+@item package-info
+Creates the @file{package-info} file from the @file{package-info.in} and
+writes an entry in the @file{package-index} file.
+
@item bindist
-Does a @code{make all} as well as create a binary package tarball in the
-staging directory.
+Builds the package, including any Texinfo documentation (info format),
+writes an entry into the @file{package-index} file and builds a tarball
+of the package. Also writes an entry into @file{setup-packages.ini}
+which is later used in the creation of netinstaller's @file{setup.ini}.
@item install
-Bytecompile all files, build and bytecompile byproduct files like
-@file{auto-autoloads.el} and @file{custom-load.el}. Create info version
-of TeXinfo documentation if present. And install everything into the
-staging directory.
-
-@item srckit
-Usually simply depends on @code{srckit-std}, with no actions. This does
-a @code{make distclean} and creates a package source tarball in the
-staging directory. This is generally only of use for package
-maintainers.
+Builds and installs a package
+
+@item install-only
+Doesn't build anything, just installs it.
+
+@item autoloads
+Generate the package's @file{auto-autoloads.el} file.
@item binkit
-May depend on @code{binkit-sourceonly}, @code{binkit-sourceinfo},
-@code{binkit-sourcedata}, or @code{binkit-sourcedatainfo}, with no
-actions. @code{sourceonly} indicates there is nothing to install in a
-data directory or info directory. @code{sourceinfo} indicates that
-source and info files are to be installed. @code{sourcedata} indicates
-that source and etc (data) files are to be installed.
-@code{sourcedatainfo} indicates source, etc (data), and info files are
-to be installed. A few packages have needs beyond the basic templates
-so this is not yet complete.
-
-@item dist
-Runs the rules @code{srckit} followed by @code{binkit}. This is
-primarily of use by XEmacs maintainers producing files for distribution.
+Creates the directories needed for installation and copies the files
+there. Basically this is an alias for @code{install-only}.
-@item clean
-Remove all built files except @file{auto-autoloads.el} and
-@file{custom-load.el}.
+@item html
+Builds the HTML versions of the documentation.
-@item distclean
-Remove all created files.
+@item compile
+Does most of the work. Builds the elcs, infos at a minimum.

simply copy @file{Local.rules.template} from that directory to
@file{Local.rules} and edit it to suit your needs.
-These are the variables in @file{Local.rules} that you will need to
-provide values for. The following variables control which packages will
-be built:
-
-@table @var
-@item XEMACS_PACKAGES
-The default is @samp{xemacs-packages}, which results in the set in
-the @file{xemacs-packages/Makefile} @code{PACKAGES} variable.
+These are the variables in @file{Local.rules} that you may need to
+provide values for:
-Otherwise, it should be a list of package source directories prefixed by
-@samp{xemacs-packages}:
+@table @samp
+@item XEMACS
+The name (and path if needed) of the XEmacs binary to use for building
+the packages. The default is @code{xemacs}.
-@example
-XEMACS_PACKAGES = xemacs-packages/xemacs-base xemacs-packages/bbdb
-@end example
+@item XEMACS_21_5
+This will enable some, as yet, unimplemented features in XEmacs 21.5 and
+above. For now leave this blank (the default) regardless of the XEmacs
+version you are using.
@item BUILD_WITHOUT_MULE
-The default is the empty value.
+Set this to @samp{t} if you are using a non-Mule XEmacs. The default is
+that this variable is not set (blank) which means to build @emph{with}
+Mule.
-Building from CVS defaults to building the Mule
-packages. Set this to 't' if you don't want/have Mule.
+@item XEMACS_NATIVE_NT
+Set this to @samp{t} if you are using a native Microsoft Windows build
+of XEmacs (not a Cygwin build) to build the packages.
+@strong{N.B.} To Windows users, you still need the Cygwin environment to
+actually build the packages.
+
+@item XEMACS_INSTALLED_PACKAGES_ROOT
+Set this to the root of where you want the packages to be installed.
+Under this directory will hang @file{xemacs-packages} and
+@file{mule-packages}. See @var{NONMULE_INSTALLED_PACKAGES_ROOT} and
+@var{MULE_INSTALLED_PACKAGES_ROOT}. The default for this is
+@file{/usr/local/lib/xemacs}. Which may not be what you want if you are
+developing XEmacs. To quote the comments in
+@file{Local.rules.template}:
+
+@quotation
+If you are developing XEmacs, you probably don't want to install the
+packages under /usr/local, which is where the stable, released version
+of XEmacs goes. Instead, we suggest a layout as described in the base
+README file of recent versions of XEmacs. In a nutshell, we suggest
+you put your source under /src/xemacs, and under this put the package
+sources in package-src/, and the installed packages in xemacs-packages/
+and mule-packages/. If you do everything this way, you might want to
+set things as follows:
+
+XEMACS_INSTALLED_PACKAGES_ROOT = $@{XEMACS_PACKAGES_BASE@}/..
+
+which puts the xemacs-packages/ and mule-packages/ directories as sisters
+of the package-src/ directory, and you have to tell configure the location
+of the installed packages using `--package-path', something like
+
+configure --package-path=/src/xemacs/xemacs-packages;/src/xemacs/mule-packages
+@end quotation
-@item MULE_PACKAGES
-The default is @samp{mule-packages}, which results in the set in
-the @file{mule-packages/Makefile} @code{PACKAGES} variable.
+@item symlink
+The default is unset (blank). If you set this to @samp{t} then
+@code{make install} will create a @dfn{symlink farm} of the installed
+packages under @var{XEMACS_INSTALLED_PACKAGES_ROOT}. Obviously, for
+this to work, your system has to support symbolic links. This is as
+close as you can get to @dfn{running in place} for the packages.
+
+@item NONMULE_INSTALLED_PACKAGES_ROOT
+This is where the non-Mule packages get installed to. The default is
+@file{$@{XEMACS_INSTALLED_PACKAGES_ROOT@}/xemacs-packages}.
+
+@item MULE_INSTALLED_PACKAGES_ROOT
+This is where the Mule packages get installed to. The default is
+@file{$@{XEMACS_INSTALLED_PACKAGES_ROOT@}/mule-packages}.
-Otherwise, it should be a list of package source directories prefixed by
-@samp{mule-packages}:
+@item NONMULE_PACKAGES
+A whitespace separated list of non-Mule packages to build/install.
@example
-MULE_PACKAGES = mule-packages/mule-base mule-packages/skk
+NONMULE_PACKAGES = bbdb gnus xemacs-base prog-modes
@end example
-@item PACKAGE_INDEX
-The default is @file{package-index}.
-
-If you want the package index file to have a different name, change
-this. This is probably a bad idea unless you are a packages release
-engineer, as it will confuse the package administration tools.
-@end table
+The value for this variable can also be the symbol
+@samp{xemacs-packages}, which means to build/install @emph{all} of the
+non-Mule packages. The default is @samp{xemacs-packages}.
-The following variables determine where files are installed and how they
-are installed. Several of the defaults use the variable
-@var{XEMACS_PACKAGES_BASE}. Never set this variable in
-@file{Local.rules}; it is automatically set in @file{XEmacs.rules}.
+@item MULE_PACKAGES
+A whitespace separated list of Mule packages to build/install.
-@table @asis
-@item @var{XEMACS_STAGING}
-The default is @file{$@{XEMACS_PACKAGES_BASE@}/../xemacs-packages}.
+@example
+MULE_PACKAGES = mule-base leim locale
+@end example
-Generic packages will be installed here. This can be the final
-destination for files or symlinks (if the packages are being installed
-locally), or a clean staging area for building tarballs.
+The value for this variable can also be the symbol
+@samp{mule-packages}, which means to build/install @emph{all} of the
+Mule packages. The default is @samp{mule-packages}.
-@strong{N.B.} @samp{make bindist} ignores this variable. It should be
-handled by the administration utilities, but currently isn't.
+@item PACKAGE_INDEX
+The name of the package-index file. The default is @file{package-index}
+and you probably don't need to worry about changing it.
-@item @var{MULE_STAGING}
+@item INSTALL
+The path to a BSD compatible install program. The default is
+@code{install -c}.
-The default is @file{$@{XEMACS_PACKAGES_BASE@}/../mule-packages}.
+@item TAR
+The path to GNU/tar. The default is @code{tar}.
-Packages requiring Mule to load correctly will be installed here. This
-can be the final destination for files or symlinks (if the packages are
-being installed locally), or a clean staging area for building tarballs.
+@item BZIP2
+The path to the bzip2 compression program. The default is unset
+(blank). If this is set @file{.tar.bz2} archives will be built
+@emph{in addition to} the @file{.tar.gz} archives.
-@strong{N.B.} @samp{make bindist} ignores this variable. It should be
-handled by the administration utilities, but currently isn't.
+@item EXCLUDES
+For things that you @emph{don't} want to go into the package tarballs.
+It takes the same format as GNU/tar's @code{--exclude} option. The
+default is:
-@item symlink
-The default is the empty value.
-
-Set this to 't' if you want to simulate ``running in place.'' It is
-currently not possible to ask XEmacs to use any package source tree as
-an automatically configured member of @code{load-path}, and it is
-unlikely that complex trees such as that of the Gnus package will ever
-be able to ``run in place.'' This variable, when set to `t', causes the
-build process to create a symlink farm otherwise identical to an
-installed tree of binary packages. Thus it is purely a space
-optimization.
-
-Setting this is incompatible with @samp{make bindist}.
-@end table
+@example
+EXCLUDES = \
+ --exclude 'CVS' \
+ --exclude 'RCS' \
+ --exclude 'SCCS' \
+ --exclude '*~' \
+ --exclude '*.orig' \
+ --exclude '*.rej' \
+ --exclude '.\#*'
+@end example
-The following variables determine how packages are made.
+@item VANILLA
+Set to the XEmacs command line option that forces running in
+@dfn{vanilla} mode. The default is @samp{-vanilla}. You wouldn't ever
+need to alter this.
-@table @var
-@item XEMACS
-The default is @samp{xemacs}.
+@item BATCH
+How to put XEmacs into @dfn{batch} mode. It also sets a couple of other
+things and in the normal course of events you wouldn't need to alter
+this from the default which is:
-The path to the XEmacs executable you wish to use to compile the
-packages and execute Lisp build scripts.
+@example
+BATCH = $(VANILLA) -batch -eval \
+ '(setq stack-trace-on-error t \
+ load-always-display-messages t \
+ load-ignore-out-of-date-elc-files t \
+ load-show-full-path-in-messages t)'
+@end example
-@item XEMACS_NATIVE_NT
-The default is the empty value.
+@item MAKEINFO
+The path to @code{makeinfo}. The default is @samp{makeinfo}
-Set this to 't' if you are building on WinNT. It controls hairy shell
-quoting in the @file{Makefile}s.
+@item INSTALL_HTML
+Set this to @samp{t} if you want to install HTML versions of the Texinfo
+documentation. The default is unset (blank).
-@item INSTALL
-The default is @samp{install -c}.
+@item TEXI2HTML
+The path to the program that can convert Texinfo source to HTML. The
+default is @code{texi2html}.
-The path to your BSD compatible install program.
+@item TEXI2DVI
+The path to the program that can convert Texinfo source to DVI. The
+default is @code{texi2dvi}
-@item TAR
-The default is @samp{tar}.

+The path to the program that can convert Texinfo source to PDF format.
+The default is @code{texi2pdf}.
-@item BZIP2
-The default is the empty value.
+@item TEX
+The path to @TeX{}. The default is @code{tex}
-If unset, bzipped tarballs will not be built. If this is set to
-something that resolves to a @samp{bzip2} executable, bzip2 tarballs
-will be built @emph{in addition to} @samp{gzip} tarballs.
+@item MSGFMT
+The path to msgfmt. The default is @code{msgfmt}
-@item MAKEINFO
-The default is @samp{makeinfo}.
+@item RCOPY

+@chapter Creating Packages:
Creating a package from an existing Lisp library is not very difficult.
In addition to the Lisp libraries themselves, you need a
-@file{package-info.in} file and a simple @file{Makefile}. The rest is
+@ref{package-info.in} file and a simple @ref{Makefile}. The rest is
done by @file{XEmacs.rules}, part of the packaging system
infrastructure.
-@file{package-info.in} contains a single Lisp form like this:

+@node package-info.in, Makefile,,Creating Packages

+@file{package-info.in} contains information that gets injected into the

-in the top directory of the packages hierarchy.
-
-An @xpms{} @file{Makefile} has three components. First, there is a
-variable definition section. The standard @xpms{} @file{make} variables
-must be defined here for use by the @file{XEmacs.rules} include file.
-Second, the file @file{../../XEmacs.rules} is included. Finally, the
-@file{make} rules are defined, possibly including additional variable
-definitions for use by the @file{Makefile}. These always include rules
-for the targets @samp{all}, @samp{binkit}, and @file{srckit}.
-
-Although a number of facilities are available for complex libraries,
-most simple packages' @file{Makefile}s contain a copyright notice, the
-variable definitions mentioned above, and some boilerplate.
+@subheading Description of the Fields in @file{package-info.in}:

-@example
-# Makefile for apackage's lisp code
+@item standards-version
+Part of the internal package infrastructure, its value should always be

+
+@item version
+This is the XEmacs package version number of the package. It is set
+from the @file{Makefile} variable @var{VERSION}. This is something that

+This is the package's internal, or @samp{upstream} version number if it
+has one. It is set from the @file{Makefile} variable
+@var{AUTHOR_VERSION}.

+@item date
+This is the date of the last change made to the package. It is
+auto-generated at build time, taken from the package's toplevel

-The @xpms{} does not automatically become aware of your package simply

+efficiency, to get the expansions inlined. In fact, it is
+@emph{impossible} to call a macro by name in byte-compiled Emacs Lisp
+code. Thus, if the macro expansion is not inlined, the call will result
+in an error at run-time! Thus, packages providing libraries that would

-This only needs to be done once, when the package is first added to the
-@xpms{}. (Well, when you randomly change the subdirectory layout, too.)
-Your changes to @file{package-compile.el} must be cleared and checked in
-by the XEmacs Package Release Engineer before your package will build
-correctly from a fresh checkout.
-
-This is unfortunate; it works pretty well once set up, but can cause
-confusion when first building a package in the @xpms{} context. In
-particular, if the @code{package-directory-map} entry for a required
-package
-@c #### including the package itself?
-is not found, the necessary requires will not be executed by
-@file{package-compile.el}. If required functions are executed (under
-@code{eval-when-compile}), they won't be found and the compile will
-fail. If required function is actually a macro, the byte compiler will
-not recognize that, compile a function call to the macro. This will
-cause a run-time error because the byte-code interpreter does not know
-how to execute macros. (Macros can always be expanded at compile-time,
-and this is more efficient.)
-
-If your package keeps some or all Lisp code somewhere other than the top
-directory, then an entry in @code{package-name-to-directory} is also
-necessary, or requires will fail, leading to the problems just described.

-The @file{package-info.in} structure is simply Lisp data, to be read by
-a Lisp script, have values substituted for variables, and then written
-out (appropriately quoted) into a loadable Lisp file, to be consed into
-the @file{package-index.el} list at the FTP archives. That list is
-structured as an alist with package names as keys. The package data is
-a plist. Do not rely on this, as it may change. If you have a good
-reason for relying on it, let the maintainers know and we may
-incorporate it in a future revision of the @xpms{} standard.
-
-There are several kinds of fields, distinguished by how they get their
-values. There are literals written into @file{package-info.in} by the
-package maintainer. There are variables substituted in by the build

-few implementation constants, some of which are simply the default value
-for obsolete fields.
-
-The @file{package-info.in} literals provided by the maintainer generally
-should not change over the life of the package. (The exception is the

+The @file{Makefile} is quite stylized. The idea is similar to an
+@file{Imakefile} or an @code{automake} file: the complexity is hidden in
+generic rules files, in this case the @file{XEmacs.rules} include file
+in the top directory of the packages hierarchy.
-The list is of @emph{packages}, not @emph{libraries}, as would
-ordinarily be provided to the Lisp @code{require} function.
+It is important to note that the XEmacs used to compile packages is
+the bare minimum: it is called with the @samp{-no-autoloads}. This
+means that anything not dumped into XEmacs by default needs to be
+specified in the @samp{REQUIRES} variable (for packaged Lisp) or in
+some cases the @samp{PRELOADS} (autoloads used in libraries mentioned
+in @samp{PRELOADS}).
-@samp{REQUIRES} cannot be correctly computed from the calls to

+There isn't much to an @xpms{} @file{Makefile}, basically it just
+contains a few @file{Makefile} variables and that's it. See the
+example.
-On the other hand, if a package provides no macros to this package, it
-is preferable @emph{not} to include it in @samp{REQUIRES}, because it is
-not uncommon that if the developer doesn't normally use the required
-package, he will never use the functionality in the package being built,
-either. In that case it would be preferable to not require the
-developer to have source for the dependencies. That said, of course it
-is safe to put too many packages in @samp{REQUIRES}.

-for the @code{all} target.
+Would put files into @file{.../etc/$(PACKAGE)/foo/}.
-@item srckit
-The target for generating a source package. Not implemented. If it
-were, the normal dependency would be @samp{srckit-std}.
+@item DATA_1_FILES ... DATA_35_FILES
+For data files that need to go into a different directory from
+@var{DATA_DEST}.
-@item binkit
-The target for creating a ``master'' installation. Binary packages are
-actually generated by the @samp{bindist} target. @xref{Building Packages}.
+@item DATA_1_DEST ... DATA_35_DEST
+The name of the subdirectory for files specified in @var{DATA_n_FILES}.
+And like @var{DATA_DEST}, be sure to prefix @samp{$(PACKAGE)} to the
+value of these variables.
+
+@item EXTRA_DEPENDENCIES
+For additional files to build that aren't appropriate to place in any
+other @file{Makefile} variable. You will need to write @file{Makefile}
+rules to build these files.
@end table
-Standard dependencies for @code{srckit} and @code{binkit} are defined in
-@file{XEmacs.rules}. The most useful of these values are given in the
-following table.
+@section @file{package-compile.el}
+@cindex package-compile.el
+@cindex compiling packages
+The @xpms{} does not automatically become aware of your package simply
+because there is a new subtree. If any package, including your own,
+requires any of your files, it must be explicitly added to the compile
+environment or loads/requires that search load-path will fail. The
+changes that need to be made are
-@table @samp
-@item srckit-std
-Build a standard source kit. Not fully implemented.
+@table @strong
+@item an entry in @code{package-directory-map}
+This tells the @xpms{} which distribution (currently
+@samp{xemacs-packages} or @samp{mule-packages}) your package is found
+in. It then looks in the distribution subdirectory whose name is the
+same as the package's.
-@item binkit-sourceonly
-The @samp{binkit} target need only install source and compiled Lisp in
-the staging area. There is nothing to install in a data directory or
-info directory.
+@item an entry in the @code{cond} in @code{package-name-to-directory}
+This is optional; it is necessary only if you keep your Lisp code
+somewhere other than the top-level directory of the package's source
+tree, eg, in @file{packages/xemacs-packages/@var{PACKAGE}/lisp}.
+@end table
-@item binkit-sourceinfo
-Both source and info files are to be installed in the staging area.
+This only needs to be done once, when the package is first added to the
+@xpms{}. (Well, when you randomly change the subdirectory layout, too.)
+Your changes to @file{package-compile.el} must be cleared and checked in
+by the XEmacs Package Release Engineer before your package will build
+correctly from a fresh checkout.
+
+This is unfortunate; it works pretty well once set up, but can cause
+confusion when first building a package in the @xpms{} context. In
+particular, if the @code{package-directory-map} entry for a required
+package, including the package itself, is not found, the necessary
+requires will not be executed by @file{package-compile.el}. If
+required functions are executed (under @code{eval-when-compile}),
+they won't be found and the compile will fail. If required function
+is actually a macro, the byte compiler will not recognize that,
+compile a function call to the macro. This will cause a run-time
+error because the byte-code interpreter does not know how to execute
+macros. (Macros can always be expanded at compile-time, and this is
+more efficient.)
+
+If your package keeps some or all Lisp code somewhere other than the top
+directory, then an entry in @code{package-name-to-directory} is also
+necessary, or requires will fail, leading to the problems just described.
-@item binkit-sourcedata
-Both source and etc (data) files are to be installed in the staging
-area.
+@node Documenting Packages, Issues, Creating Packages, Packaging
+@comment node-name, next, previous, up
+@cindex documenting packages
+@heading Documenting Packages:
-@item binkit-sourcedatainfo
-Source, etc (data), and info files all are present and need to be
-installed in the staging area.
+@c #### Add a documentation section to Internals, and xref here.
+Some random notes on documenting your package.
-@item binkit-common
-A dependency for all the above. (In fact in the current implementation
-@samp{binkit-common} does all the work for all of the @samp{binkit}
-targets.)
-@end table
+Do write a Texinfo file. It's not that hard to do basically, and even
+using the more advanced features of Texinfo soon become natural. For a
+start, just grab the template @file{Samples/package.texi} from the
+@xpms{} source tree, and drop your current README into the Top node. At
+least this way your documentation will be accessible from the standard
+Info readers. Next, try to add lots of cross-referencing and logical
+markup, and then node structure.
+
+Address both end users and developer issues. You may not be the
+maintainer forever.
+
+If you are maintaining a package that is part of the GNU Emacs
+distribution, you'll likely find that you occasionally synchronize your
+package with the GNU Emacs sources. When you synch a file,
+conventionally you should place a comment just above the standard
+@code{;;; Code} comment that looks like this:
+
+@example
+;; Synched with:
+;; GNU Emacs 21.1, 2002-02-08, Stephen Turnbull <stephen@@xemacs.org>
+@end example
-Data files include things like pixmaps for a package-specific toolbar,
-and are normally installed in @file{etc/@var{PACKAGE_NAME}}. A few
-packages have needs beyond the basic templates. See @file{XEmacs.rules}
-or a future revision of this manual for details.
+This comment is a status flag; the ChangeLog doesn't really give the
+same information.
+Do maintain a detailed ChangeLog.
