genpath_exclude

Executes like genpath, but can ignore specified directories.

Description

Executes like genpath, but can ignore directories. Useful to add a directory hierarchy to your path, but ignore CM directories such as "CVS" or ".svn"

Directories may be excluded using regular-expressions as well.

Tested on windows only, but should work on any platform.

Example usage:
genpath_exclude('C:\myDir',{'CVS'}) %<--- simple usage to ignore CVS direcotries

genpath_exclude('C:\myDir',{'\.svn'}) %<--- simple usage to ignore .svn (note that "." must be escaped for proper handling in the regexp)

genpath_exclude('C:\myDir',{'CVS','#.*'}) %<----more advanced usage to ignore CVS directories and any directory starting with "#"

I think regexp with option 'split' is quite new.=>This may not work with R14 or previous.
For optimization why don't you modify directly genpath to not go into excluded directories?

Thanks for the comment Thierry. I did look at modifying genpath, and for some reason on my first attempt, the excluded path would still be added, but not the tree beneath it. That is when I went off looking into the regexp business to remove the offending paths.

Taking a second look, I realize that it is possible to modify genpath directly accomplish this goal, which should operate faster since it wouldn't recurse on the ignored directories.
