Supporting code for creating packages and metapackages for UCSC executables.
The script create-ucsc-packages.py downloads the program listing from UCSC,
downloads the source code, and creates recipes for every identified program
(currently 115 in v324). There are some special cases handled by the script.
The script uses the templates in this directory to be able to compile the tools
individually in each recipe.
Change the VERSION variable at the top of the script to update the packages
when a new version comes out.
