This macro is used when handling directories with OPEN_MENU, e.g., to list
available image files for setting the workspace background.
When parsing a menu file, we replace any instances of #usergnusteppath#
with either GNUSTEP_USER_ROOT or ~/GNUstep if the former is not set. In
this way, authors of menu files do not have to worry about whether users
will have this variable set or not.
We also document this feature in WindowMaker/menu.in, which generates the
default English language old-style menu and currently contains the existing
documentation for the Window Maker menu system.
The path to WPrefs has been hardcoded in many of the menu files to
/usr/local/GNUstep/Applications/WPrefs.app/WPrefs, which would only actually
work if the user ran something like:
./configure --with-gnustepdir=/usr/local/GNUstep
during build.
Instead, we add a .in extension to all menu files with this issue and use sed
to use the actual WPrefs path (given by the wprefs_bindir output variable) and
generate a new menu file.
A very similar idea is already used to generate the WMState file, which sets
WPrefs as the command for the Window Maker logo tile in the dock.
