# Make release tar files for some or all lists. Usage:
2002-12-26 02:44:06 +03:00
# maketars [-b] [-x] [-i installdir] [-a arch] [-m machine] [-s setsdir]
# [-M metalog] [-N etcdir] [-d destdir] [-t tardir] [setname ...]
#
2002-12-26 02:47:32 +03:00
# The default sets are "base comp etc games man misc text"
# The X sets are "xbase xcomp xetc xfont xserver"
2002-12-26 02:47:32 +03:00
#
# 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.

2003-01-03 18:26:32 +03:00
[-M metalog] [-N etcdir] [-d dest] [-t targetdir] [setname ...]
-b Make both netbsd and x11 lists
-x Only make x11 lists
[Default: make netbsd lists]
-i idir Install sets to idir instead of creating tar files
-a arch Set arch (e.g, m68k, mipseb, mipsel, powerpc) [${MACHINE_ARCH}]
-m machine Set machine (e.g, amiga, i386, macppc) [${MACHINE}]
-s setsdir Directory to find sets [${setsdir}]
-S Exit after creating set files ${dest}/etc/mtree/set.*
-M metalog metalog file
-N etcdir etc dir for metalog use [${dest}/etc]
-d dest \${DESTDIR} [${dest}]
-t targetdir \${RELEASEDIR} [${tars}]
