I use case statements wherever possible instead of 'test'.
While 'case' is a shell builtin, 'test' may not be. If there are a
bunch of checks being done, it can be significantly faster to use 'case'
instead of 'test'.
Disclaimer: I have been doing this for Years (I picked it up from Larry
Wall sometime before I took over the maintenance of metaconfig) and have
not tested it lately.
