Mixing Installed Stack with Development Repositories

When contributing to development work it is often useful to use most packages from an installed stack and only keep local copies of the repositories that need workIf you are going beyond simply using software packages provided by LSST and need a direct git clone of a particular repository (because you wish to contribute development work directly back into repository or because a new feature is available but has not been released officially yet), you can mix an installed stack with development repositories. For pure python packages, this is straightforward.  The following steps will put a local copy of the sims_maf git repository into a pre-existing stack.   **Note you do not have to do this just to install and use any sims package, such as MAF.

All packages may be declared with a version and a tag.  The version distinguishes on instance of a particular package from another.  The eups tag can be used to define a coherent set of packages.  The philosophy is to tag all personal package (packages downloaded via git) with a custom tag using the username.  Using this workflow allows packages to be set up with the -t $USER switch which means that custom packages are used if they are declared and main stack packages are used otherwise.
