one-file
compiles, appends source file that contains compile instructions
one-file (1f) project is a collection of utilities and tools primarily written for console use, with text output, or using SDL 1.2 for framebuffer "gui stuff".
When individually compiled, the source is appended, either as TEXT, or ZIP, to the resulting binary. That source contains command line options to extract that source, as well as the command line used to compile said source.
There are no hard and fast rules, except "name-1f", must append source, and source must contain compile time...
