-Note that for most of the following options, you can explicitly enable

+CONFIGURATION is an optional architecture-vendor-os triple, such as
+`sparc-sun-solaris2.7'. When possible, omit it; configure will detect it.
+
+Conventions for options:
+- Boolean options may be explicitly enabled by using `--OPTION=yes' and
+ explicitly disabled by using `--OPTION=no'. `--OPTION' (with no argument)
+ is equivalent to `--OPTION=yes'. `--without-FEATURE' is a synonym for
+ `--with-FEATURE=no'. Denoted `(Bool)' below.
+- Enumerated options accept one type from a specified list. These usually
+ accept `--OPTION=no' to disable it entirely, and `--OPTION=yes' often has a
+ useful default. Denoted `(Enum)'.
+- Set options accept one or more types from a list of implementations of the
+ feature. All specified implementations will be included. Prefix a type
+ with `no' to disable only that implementation (e.g., `--with-sound=nonas'
+ to disable NAS). The special values `none' and `all' must be first in the
+ list if used. They change the defaults for all types individually from
+ autodetect to `no' or `yes' respectively. `--with-sound=none,native' and
+ `--with-sound=noesd,nonas,native' have the same effect. Denoted `(Set)'.
+- Other options have special, option-specific formats.
+
+Options marked with a (*) are auto-detected. If auto-detected and not
+explicitly specified, normally
+- Boolean options default to `yes'.
+- Enumerated options default to the first detected type in an option-specific
+ priority. Possible defaults are marked with (*) and listed in order.
+- Set options default to all detected types.
+
+Some options are provided mainly to disable features which are on by default.
+These are indicated by specifying `--OPTION=no'. Explicitly specifying an
+autodetected option which defaults to `yes' makes a failure to detect signal
+a fatal configure error.
Use colons (or quoted spaces) to separate directory names in option
values which are PATHs (i.e. lists of directories).
+Many features require external packages to be installed. configure will fail
+if an explicitly requested feature depends on an uninstalled package. On many
+Linux systems, you must install -devel versions of the package.
+
The results of configure tests are saved in config.log, which is useful
-for diagnosing problems.
+for diagnosing problems. Caching of configure results is disabled.
+If successful, configure leaves its status in config.status. If
+unsuccessful after disturbing the status quo, it removes config.status.

+ dynamically linked libraries at run time
+--dynamic (*) (Bool) Link dynamically if supported by system.
+ The default is system-dependent.

- executable.
+--with-prefix=no (Bool) Compile the value of `--prefix' into XEmacs.
+--infodir=DIR Install XEmacs Info manuals and dir in DIR.

+including `--bindir', `--libdir', `--docdir', `--lispdir', `--sitelispdir',
+`--datadir', `--mandir' and so on. These options are DEPRECATED; see INSTALL.

+ `site-modules' before the installed module directories.
+--with-site-lisp (Bool) Search a site-lisp directory in the XEmacs
+ hierarchy before the packaged Lisp. DEPRECATED.

+ the `late' part somewhere in the middle, and the
+ `last' part at the very back.
+ Only the `late' part gets seen at dump time.
+ If PATH has only one component, it is `late'. With two

Window-system options:

+
+GUI component options:
+
+Select the widget set used to implement components, Lucid, Motif, or Athena.
+If `--with-gtk', `--with-gnome', or `--with-msw' are used or implied, treat
+component options as Bool. The `lucid' widgets are a homebrew set, emulating
+Motif but faster. Lucid toolbars, menubars, and scrollbars are implemented
+in Xt. Lucid dialogs and misc widgets wrap and enhance Motif (or Athena if
+Motif is not found). Several enhanced (eg, 3d) Athena libraries may be used,
+but the default is the X11R6 `libXaw' (flat) widgets. Use `--with-athena' to
+explicitly specify which library to link against.
+
+--with-toolbars=no (Bool) Don't compile with any toolbar support.

---with-widgets=TYPE Use TYPE widgets (motif, athena, or no).
- Motif widgets will be used if Motif can be found.
- Other widget types are currently unsupported.
---with-dragndrop Compile in the generic drag and drop API. This is

- protocols is found (currently CDE, OffiX, MSWindows).
- *WARNING* The Drag'n'drop support is under development
- and is considered experimental.
---with-cde Compile in support for CDE drag and drop.
---with-offix Compile in support for OffiX drag and drop.
- *WARNING* If you compile in OffiX, you may not be

- fully. If the two servers are from
- different vendors, the results may be
- unpredictable.
---with-xmu=no (*) For those unfortunates whose vendors don't ship Xmu.
---external-widget Compile with external widget support.
+--with-scrollbars=TYPE (Enum) Types: `lucid'(*), `motif', `athena', or `no'.

Image options:
---with-xpm (*) Compile with support for XPM images. PRACTICALLY
- REQUIRED. Although this library is nonstandard and
- a real hassle to build, many basic things (e.g.
- toolbars) depend on it, and you will run into
- many problems without it.
---with-png (*) Compile with support for PNG images. Recommended
- because the images on the About page are not viewable
- without it.
---with-jpeg (*) Compile with support for JPEG images. Useful if
- you are using a mail, news reader, or web browser
- in XEmacs, so that JPEG images can be displayed.
---with-tiff (*) Compile with support for TIFF images. Possibly
- useful, for the same reason as JPEG images.
---with-xface (*) Compile with support for X-Face mail headers.

with `--with-sound=native,nas' because both sound
libraries are called libaudio.
Database options:
---with-database=TYPE (*) Compile with database support. Valid types are
- `no' or a comma-separated list of one or more
- of `berkdb' and either `dbm' or `gnudbm'.

- searched before the installation packages.
---with-site-modules=no Disable site-modules directory in the XEmacs hierarchy,
- which is searched before the installation modules.

- needed to support non-Latin-1 (including Asian)
- languages.

- Use either raw Xlib to provide XIM support, or
- the Motif XmIm* routines (when available).
- NOTE: On some systems bugs in X11's XIM support
- will cause XEmacs to crash, so by default,

+--use-regex-malloc=no (Bool) Use malloc (not alloca) for regex fail stack.
+ Setting this to 'no' allows crashes - it may be
+ impossible to detect stack exhaustion, and your
+ XEmacs will crash.
Debugging options:

+--debug (Bool) Compile with support for debugging XEmacs.
(Causes code-size increase and little loss of speed.)
---error-checking=TYPE[,TYPE]...

determine what XEmacs's memory is being used
for. Causes a small code increase but no loss

---no-doc-file Don't rebuild the DOC file unless it's explicitly
- deleted. Only use during development. (It speeds
- up the compile-run-test cycle.)
---use-union-type Enable or disable use of a union, instead of an
