+has-module
+==========
 
-Base git repo for a python project
+Simple tool for checking if a python module is installed.
 
-You'll want to edit:
+`has-module module_name [version]`
 
-* Rename `package` directory
-* name, description, package module, and scripts in `setup.py`
-* docker image name in `Makefile`
-* entrypoint script name in `Dockerfile`
+* If the python module named by `$module_name` is not installed, return exit code 1.
+* If `$version` is supplied and the installed module's version doesn't match it, return exit code 1.
+* Otherwise, the module was successfully imported and the exit code will be 0.
