gh-get
Create a directory from a github repo, with the repo name and
release version (or commit hash) in the dir name.
Usage:
gh-get https://github/com/user/repo
gh-get user/repo
should create a dir called ./$repo-$version or ./$repo-$commit_hash
What's it for?
This script makes it much easier to package up stuff from GitHub as a PET file.
It does this by making one of the initial steps easier - specifically, by automating
the creation of a folder with version number, which is needed if you wanna
use new2dir, and dir2pet.
Background info
When compiling packages, you can use the command new2dir make install,
and the new2dir script will install your newly compiled program into its own
folder, ready to be packaged up as a PET.
One problem - new2dir requires a version number in the folder name of the
program being compiled, and if you download a .tar.gz from GitHub, or clone
a GitHub repo, then you don't get the version numbers in the folder name.
Even worse, many github projects don't store a version number at all - you
need to get the latest commit hash, of the latest branch, and use that.
The script
Save as /usr/bin/gh-get

I intend for this script to end up in Petbuild or Pkg, so we can automate the packaging of various kinds of github repos into PET packages.
