There is NO official repository for scripts. However, individuals create some
repositories, of various stuff. However what one person finds useful, others
may need to modify for their own use. So caution is recommended.
Ideally the scripts should be self-documenting and clearly written, and the
ones here are generally like that.
Some Examples Scripts installed in '/usr/share/docs/...'
as part of the IM installation (or in the IM sources).
