Many files in icewm are searched in library path. The path contains the following directories:
user's personal customization
system-wide customized defaults
compiled-in default directory with default files (for .rpm packages the default is /usr/X11R6/lib/X11/icewm)
The directories are searched in the above order, so any file located
in the system/install directory can be overridden by the user by creating
the same directory hierarchy under $HOME/.icewm.
