   3 # This script can be used by a cron to generate snapshots.
   4 # For example, use:
   5 # 35 0 * * * mkdist -r elinks-0.11 -l 0.11 -s >>mkdist.log 2>&1
   6 # 40 0 * * * mkdist -r HEAD -l 0.12 -s >>mkdist.log 2>&1
   7 #
   8 # Options:
   9 #   -g GIT_DIR   Git repository from which this script exports ELinks.
  10 #                May be given in the environment instead.
  11 #   -r REVISION  Git revision to be exported from the repository.
  12 #   -l LABEL     User-friendly name of the branch or release.
  13 #                This ends up in the name of the tar file, and in the
  14 #                name of the directory it contains.
  15 #   -s           Generate a snapshot (which has a date in the top-level
  16 #                directory).
  17 #   -d DOCDIR    Copy prebuilt documentation from DOCDIR.
  18 #   -o OUTDIR    Place the output files in OUTDIR.  Defaults to the
  19 #                current directory.
