+## Usrup
+
+Usrup is a small script for managing you $HOME/src directory.
+I find it often that in addition to packages installed with
+my package manager I have programs I clone and use that
+I would like to keep up to date. The script usrup.sh will do
+the following:
+
+* Define some helpful functions
+* Change directories in to the parent source dir
+* Source a user defined file for defining what repos exist and building them
+
+The actions defined in the user supplied file will run the build commands.
+Each build is executed in parallel, when finished the script will print
+'done'. It's important to note that Usrup is not a build system for your
+project, but rather a system for updating and invoking the different
+build systems of various objects.
+
+### Config
+
+The example.sh contains example of some various different repo
+configurations. `git_repo_do` and `usrup_do` are defined as the action functions.
+There are also utility functions provided as a short hand alias for common
+build systems. The comments in `usrup.sh` contain some more detailed information.
+
+
+### Running
+
+`sh usrup.sh /home/moody/src /home/moody/lib/usrupconfig.sh`
+
+This defines `/home/moody/src` as the parent dir with with the projects
+underneeth it and uses `/home/moody/lib/usrupconfig.sh` for defining the build
+methods for each project.
