@mintuz gist contains instructions of how to preserve history of a subdirectory between repos, for example a template or lib within morph-renderer
which you are transferring into morph-modules
.
However this script doesn't work for a whole repository, such as something already (incorrectly) versioned or a standalone lib.
Based off of article found here: http://www.nomachetejuggling.com/2011/09/12/moving-one-git-repo-into-another-as-subdirectory
You have two repos here. morph-modules
and my-module
. We will be copying 'my-module' and preserving it's history into morph-modules/my-module
.`
