# This file is used to reset your environment. This is needed if you
# want to change LIBRARY_COMBO. You first reset your environment, then
# set a new LIBRARY_COMBO variable, then source GNUstep.sh again.
# This file resets variables in reverse order as they are set in the
# GNUstep.sh file.
# This file only makes sense if you are using the standard GNUstep
# filesystem structure. If you're not, then your System Tools
# directory could be /usr/bin, but you don't really want to remove
# that from your PATH. :-)
# This function resets a path.
# It takes two arguments: the name of the path variable to reset,
# and a path fragment which is used to make our guess at what should
# be removed more accurate. All paths beginning with GNUSTEP_SYSTEM_ROOT,
# GNUSTEP_LOCAL_ROOT, GNUSTEP_NETWORK_ROOT and GNUSTEP_USER_ROOT
# followed by the specified path fragment are removed from the path
# variable. All other paths are kept unchanged.
