# Make release tar files for some or all lists.  Usage:
# maketars [-b] [-x] [-i installdir] [-a arch] [-m machine] [-s setsdir]
#	[-M metalog] [-N etcdir] [-d destdir] [-t tardir] [setname ...]
#
# The default sets are "base comp etc games man misc text"
# The X sets are "xbase xcomp xetc xfont xserver"
#
# If '-i installdir' is given, copy the given sets to installdir
# (using pax -rw ...) instead of creating tar files.
# In this case, remove "etc" and "xetc" from the list of default sets.
