[Bashdb-devel] Re: [PATCH] fix bashdb script handling of tmp directory

[R. Bernstein]

I've been meaning to thank Eric Blake for packaging the bash debugger
on cygwin (where others previously had either no interest or gave
up). So thanks!

That said, this bug report isn't relevant to full-fledged bash
debugger, but the older pot-bellied pig debugger which is included in
the bash distribution. In the past that code was a bit lacking,
probably still is and should be discarded (but given past history
probably won't be for a long time). The debugger from
http://bashdb.sourceforge.net in fact does understand "bashdb -V" and
"bashdb -h"

I'm sorry for the confusion of names that both are called bashdb. But
in truth there are probably a couple more bashdb's of historical
importance (unless you're running an old version of bash) which are
out there as well.  In the past, I tried calling the project rebash,
and source-code include files have been renamed from bashdb-main.inc
to dbg-main.inc. But alas confusion persists and I don't know how to
reduce it without a lot of work.

Finally, I should note that when submitting patches having them quoted
like this:

just makes it harder to apply the patch.
