quick hack demonstrating use of CmdCp easyblock to build VisIt

see subject
If I don't skipstep 'source', I get 

"EasyBuild crashed with an error (at easybuild/tamusc/python_virtenv/lib/python2.6/site-packages/easybuild_framework-1.14.0-py2.6.egg/easybuild/tools/filetools.py:523 in extract_cmd): Unknown file type for file /software/easybuild/sources/v/VisIt/build_visit2_7_3 (['build_visit2_7_3'])")"

There is no source to unpack (it is just a bash script).
