Mercurial hgignore

[Sean]

Hi,

I am new too Mercurial (got spooked by the darcs hanging issue) and am
having a bit of trouble with the regexp / glob syntax of .hgignore

Can someone please advise (or point me to a decent guide on glob
syntax) if there is a case insensitive way of ignoring file types ?

For instance, there must be a simpler way of doing this sort of thing:

*.jpg
*.JPG
*.jpeg
*.JPEG
*.png
*.PNG

Additionally, in trying to ignore certain subdirectories, I am using
this syntax (windows):

*enc\
*opt\

which seems to be working. Is this correct ?

With regard extensions and other setting in the mercurial.ini, does
anyone know how to use relative, rather than absolute paths ?

The following work, but are not very portable.

ignore = f:\mercurial\.hgignore.global
keyword = f:\mercurial\hgext\keyword.py

If there is no better way, I will try setting the path to mercurial in
the environment.

TIA
