# getmap - unshar usenet map articles into the UNSHAR_MAP_DIR directory
#
# usage: getmap [-m mapdir] [-w workdir] [-b batchfile] [-u username]
#
# -m mapdir - 'mapdir' is where maps are unpacked,
# by default 'mapdir' is $UNSHAR_MAP_DIR
# -w workdir - where logs and default batch files are kept,
# by default 'workdir' is 'mapdir'/work
# -b batch - 'batch' is a file of filenames to unshar,
# '-' impiles read filenames from stdin,
# by default 'batch' is 'workdir'/batch
# -u username - errors are Emailed to 'username' rather than
# Posmaster, the username '-' imples that
# the errors should be written to standard error
# -n newsgroups - allowed newsgroups for articles
#
# unsharmap errors will be emailed to the postmaster.
#
# default files:
# $UNSHAR_MAP_DIR - maps are unpacked here
# $UNSHAR_MAP_DIR/work/getmap.log - log of getmap activity and errors
# $UNSHAR_MAP_DIR/work/getmap.err - like getmap.log + skipped lines
# removed if no major unshar errors
# $UNSHAR_MAP_DIR/work/batch - default list of artciles to unshar
# batch.work - tmp copy of batch work, normally
# $UNSHAR_MAP_DIR/work/batch.work,
# ignored if "-w -"
# locations and constants
