-dnl Synopsis: mdw_DEFINE_PATHS(CODE)
-dnl
-dnl Arguments: CODE = shell script code to execute
-dnl
-dnl Use: Fixes up various variables so that pathname defines can be
-dnl defined. Within CODE, you may use the following macros:
-dnl
-dnl mdw_PROG(NAME) Transformed program name
-dnl
-dnl mdw_PATH(PATH) Expanded path (may contain variables)
-dnl
-dnl mdw_DEFINE_PROG(SYMBOL, PROG)
-dnl Define a symbol as a transformed
-dnl program name.
-dnl
-dnl mdw_DEFINE_PATH(SYMBOL, NAME)
-dnl Define a symbol as an expanded path
+### 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)'.
