.x

I once gave a bad revioew to a UNIX book that suggested that executables should have a .x suffix.

But I find myself using the .x suffix, in large part because I want to automatically .hgignore (or .cvsignore, or ,gitignore) executables created by tests.

I *do* only tend to use .x for test executables. I prefer not to have to type in foo.x to use the tool foo. Although sometimes I will create a script foo that invokes foo.x.

I sometimes wonder about a suffix path as well as the directory path.
