## The recurrent (^|/) idiom in the regexps below should be understood
## to mean "at any directory" while the ^ idiom means "from the
## project's top-level directory".

## gnulib related files
(^|/)gnulib$
# This directory gets created by gnulib during the build.
(^|/)libgnu$
# gnulib makes these silly backup files.
.~$

## m4 related files
# This directory mostly contains cruft during build time, but it does
# contain some Octave code, so be more careful about what we ignore here.
^m4/(?!ax_).+\.m4$
