The UNIX System V User Reference Manual documents the C preprocessor
under CPP(1). It also warns you that the C preprocessor is intended
only for use via "cc" with C sources and that any other use may
break some day. I assume this refers to the possibility of bundling
the CPP functions into the lexical analyzer where they belong.
