# Warning - this shell script is delicate, because it is sourced by
# using . rather than simply executed.  It is sourced because that is
# the only way to change the shell variables in the calling
# environment.
#
# Sourcing makes the shell script more delicate for the following reasons:
#
#  * temporary variables are automatically set in the calling
#  environment!  WORKAROUND: we need to unset all them after using
#  them to avoid polluting the calling environment;
#
#  * not only the exit value of the script, but the exit value of each
#  command we execute, might be interpreted by the calling
#  environment.  Typically, the calling environment might be using the
#  shell errexit option ('set -e') in bash parlance, which causes the
#  shell to exit if any command returns an error value.  If this were
#  a normal script, this option would mean that the shell would exit
#  if the return value of the whole script were an error value; but
#  because we are sourced, it is as all the commands in this script
#  were executed directly in the calling environment, so *all* values
#  returned by *all* commands must be non-error.  [this all typically
#  happens in rpm builds, where scripts are run with the errexit
#  option so that errors in scripts abort the build, and now if a
#  script sources GNUstep.sh, then we are exactly in this situation -
#  if any command inside GNUstep.sh returns an error value (even if
#  GNUstep.sh as a whole would be happy and return succes), the whole
#  rpm build process aborts!]. WORKAROUND: we must make sure all
#  commands return success - last resorts hacks like 'command || :'
#  which always returns success whatever command returns.
#
