# SUBDIRS lists the components of Elk that are compiled and installed by
# running "make" and "make install".  The subdirectory "src" holds the
# interpreter proper; a mininum configuration requires the SUBDIRS include,
# scripts, src, and scm.
#
# Subdirectories if lib/ hold the standard extensions.  Delete them or
# parts of them from SUBDIRS if you don't want them to be compiled and
# installed; delete lib/xm and lib/xm/xt if you don't have Motif on your
# system.
