Package: dc
Version: 1.06.94-3
Severity: wishlist
Tags: patch
The dc package in Debian etch and earlier had a patch that added support
for a .dcrc file, which was run on startup. This was a really great
feature (I use it, for example, to run '3k' when starting up, so that dc
will return more precision than just integers). It would be nice if it
could be returned to the newer release.
I've taken the patch from the old version of dc, applied it to the
latest release and attached it to this report.
Many thanks,
Paul
