if [ "${1}" = '-h' -o "${1}" = '--help' ]; then
    echo "${0} (Long Time No Upload) queries the public mirror of the
Ultimate Debian Database (UDD) for all uploads of packages by the
given uploader or maintainer and displays them ordered by the last
upload of that package, oldest uploads first.

The maintainer/uploader to query can be given either by setting
\$DEBEMAIL as environment variable or as single commandline parameter.

If a commandline parameter does not contain an \"@\", \"@debian.org\"
is appended, e.g. \"${0} abe\" queries for \"abe@debian.org\".

Exceptions are some shortcuts for common, long e-mail addresses. So
far implemented shortcuts:

* pkg-perl = pkg-perl-maintainers@lists.alioth.debian.org
* pkg-zsh  = pkg-zsh-devel@lists.alioth.debian.org
* pkg-gnustep = pkg-gnustep-maintainers@lists.alioth.debian.org
