### SYNOPSIS
###
###   mdw_DEFINE_PATHS(BODY)
###
###   mdw_PROG(PROG)
###   mdw_PATH(PATH)
###   mdw_DEFINE_PROG(SYMBOL, PROG)
###   mdw_DEFINE_PATH(SYMBOL, PATH)
###
### DESCRIPTION
###
###   This collection of macros is useful for hardcoding pathname strings
###   into binary programs.
###
###   Within the BODY of `mdw_DEFINE_PATHS', a number of variables are `fixed
###   up' so that they can be properly expanded.  The other macros are only
###   really useful within this body.
###
###   `mdw_PROG' expands, in the shell, to the transformed name of the
###   program PROG.
###
###   `mdw_PATH' expands, in the shell, to the recursive expansion of PATH,
###   which should be a string containing parameter expansions.
###
###   `mdw_DEFINE_PROG' is a convenience macro which defines the preprocessor
###   SYMBOL to the result of `mdw_PROG(PROG)'; similarly `mdw_DEFINE_PATH'
###   defines SYMBOL to the result of `mdw_PATH(PATH)'.
