git_tree 0.3.0

Installs 3 commands that process a git directory tree. Directories containing a file called .ignore are ignored. The git-tree-replicate command writes a script that clones the repos in the tree, and adds any defined remotes. The git-tree-evars command writes a script that defines environment variables pointing to git repos. The git-tree-exec command executes a bash expression on children of a directory, or a list of directories.
