woman-path

woman-path is a variable defined in `woman.el'.
Its value is

nil

Documentation:
List of SPECIFIC DIRECTORIES to search for UN*X manual files.
For example

("/emacs/etc").

These directories are searched in addition to the directory trees
specified in `woman-manpath'. Each element should be a directory
string or nil, which represents the current directory when the path is
expanded and cached. However, the last component (only) of each
directory string is treated as a regexp (Emacs, not shell) and the
string is expanded into a list of matching directories. Non-directory
and unreadable files are ignored. The default value is nil.

Any environment variables (which must have the UN*X-style form $NAME,
e.g. $HOME, $EMACSDATA, $emacs_dir) are evaluated first but each
element must evaluate to a SINGLE directory name (regexp, see above).
For example

("$EMACSDATA") [or equivalently ("$emacs_dir/etc")].

Trailing `/'s are discarded. (The directory trees in `woman-manpath'
are also searched.) On Microsoft platforms I recommend including
drive letters explicitly.

You can customize this variable.
