  95 This builds Koha deb packages, from a git snapshot. It's not suitable for
  96 making upstreamable verions, but handy for your own local packages.
  97
  98 Options:
  99     --buildresult, -r
 100         the location that the resulting .deb, .changes, etc. will be placed in.
 101         Default is whatever pdebuild uses.
 102     --distribution, -D
 103         the distribution value to set in the changelog when editing it. Default
 104         is 'squeeze-dev'.
 105     --git-checks, -g
 106         what level of git checks are run to determine if the working copy is
 107         clean enough. One of 'all' (any changes are bad), 'modified' (only
 108         tracked files with untracked changes will cause an error), and 'none'
 109         (checking git status is skipped totally.) Default is 'all'.
 110     --version, -v
 111         the version string for the resulting package. Default is '$version'.
 112     --(no)autoversion
 113         whether or not to use the date and git commit ID in the version value.
 114         Default is to include it.
 115     --debug, -d
