- # Note that all options except "Naming Conventions" and certain library
- # functions may be left blank or omitted entirely; the defaults are intended
- # to encompass a wide variety of "reasonable" implementations of C.
- # Option names are case-insensitive.
- # The single-valued options can all be overridden by a later line in
- # this file, or in your own "p2crc" or ".p2crc" file, or in comments
- # in the input file. To override an explicit value with the original
- # default, use the word "def".
- # Some options define printf-like format strings. These support all the
- # usual formatting codes, with additional features for string formatting.
- # The following extra "flag" characters are defined for %s:
- # _ Convert to lower case
- # ^ Convert to upper case
- # _^ Convert to lower except capitalize first char and after non-letters
- # ~ Insert '_' between lower case and following upper case letters
- # ! Remove '_' and other non-alphanumeric characters
- # ? Negates _ and ^ flags if name contains mixed case
- # R Remove file name suffix (e.g., "foo.pas" => "foo")
- # / Remove path name (prefix ending in /, , ], or :)
- # Also, where a format includes several "%" arguments, they may
- # appear in either order in the string. When two string args are
- # involved, "%s" will refer to one and "%S" to the other. The
- # notation %H expands to the p2c home directory name, as in "%H/p2crc".
- # Many options simply refine defaults controlled by the Language,
- # AnsiC, and Target options.
