cg-export - exports a particular revision from a git repository
cg-export DESTFILE [TREE_ID]
Takes a destination and optionally a tree ID as a parameter, defaulting to HEAD.
The destination can be either a .tar, .tar.gz, .tar.bz2 or .tgz for generating a tarball. Other destination specifiers are assumed to be directory names, and the tree is exported to the given directory.
