To check out a specific (tagged) version of the CRAM system, you can use this script to automatically clone the source code from the GitHub repositories and check out the correct version tag. This file should be downloaded into the directory where your cram packages are stored:

cram_tag_co.sh

#!/bin/bash

To download the latest version (assuming the script is in the file cram_tag_co.sh), do first give execution rights to the script and then run it:

$ chmod +x cram_tag_co.sh
$ ./cram_tag_co.sh

The latest version might include changes that are not yet part of the full-fledged tagged version. Be sure to always check out the current code when there is no pressing reason to download a specific tagged version.

To download the code and check out version v0.1.1, do this (assuming the script is in the file cram_tag_co.sh):

$ chmod +x cram_tag_co.sh
$ ./cram_tag_co.sh v0.1.1

You can then find the downloaded and checked out files in their respective subdirectories. In case the repositories were downloaded already, only differing changes are downloaded from GitHub. The version tag is then checked out on each repository.
