XEmacs deals with a multitude of files during operation. These files
are spread over many directories, and XEmacs determines the location of
most of these directories at startup and organizes them into various
-paths. (A @emph{path},

XEmacs has quite complex procedures in place to find directories, no
matter where they may be hidden.
XEmacs will always respect directory options passed to @code{configure}.
However, if it cannot locate a directory at the configured place, it
will initiate a search for the directory in any of a number of

parts of the XEmacs installation; it may locate several such hierarchies
and search across them. (Typically, there are just one or two
hierarchies: the hierarchy where XEmacs was or will be installed, and
the one where it is being built.) Such a directory containing a

XEmacs locates packages in any of a number of package hierarchies.

It is possible to specify at configure-time the location of the various
package hierarchies with the @code{--package-path} option to configure.
Here is a list of the various directories and paths XEmacs tries to
locate during startup. XEmacs distinguishes between directories and

under @file{<root>}, because that is where they are in the XEmacs tarball.
