This script shows the downloads count of the GitHub repositories.
You must put the archive file in a GitHub release, an example is on GitHub Blog - Release Your Software.
In order to get the downloads count of all GitHub repositories of a specific user, you need to execute:
./gdc github-username
You can specify a single project:
./gdc github-username github-projectname
Example:
./gdc rethinkdb
output is:
rethinkdb-1.7.0.dmg: 454 downloads
rethinkdb-1.7.0.i686.rpm: 449 downloads
rethinkdb-1.7.0.x86_64.rpm: 450 downloads
rethinkdb-1.6.1.dmg: 455 downloads
