()

The plugin formerly known as Map Color Range in GIMP 2.2 and Color Range Mapping in GIMP 2.4 appears to have been removed in GIMP 2.6.

One way to get it back is to just grab the plug-in file from a previous version.  For example, you can run:

wget http://download.fedora.redhat.com/pub/fedora/linux/releases/9/Everything/i386.newkey/os/Packages/gimp-2.4.5-1.fc9.i386.rpm

rpm2cpio gimp-2.4.5-1.fc9.i386.rpm|cpio -idvm

git ls-files --others -i --exclude-standard

Git 1.4, 1.5:
git ls-files --others -i \
--exclude-from="`git rev-parse --git-dir`/info/exclude" \
--exclude-per-directory=.gitignore
