3 | ### SYNOPSIS |
4 | ### | |
5 | ### mdw_DEFINE_PATHS(BODY) | |
6 | ### | |
7 | ### mdw_PROG(PROG) | |
8 | ### mdw_PATH(PATH) | |
9 | ### mdw_DEFINE_PROG(SYMBOL, PROG) | |
10 | ### mdw_DEFINE_PATH(SYMBOL, PATH) | |
11 | ### | |
12 | ### DESCRIPTION | |
13 | ### | |
14 | ### This collection of macros is useful for hardcoding pathname strings | |
15 | ### into binary programs. | |
16 | ### | |
17 | ### Within the BODY of `mdw_DEFINE_PATHS', a number of variables are `fixed | |
18 | ### up' so that they can be properly expanded. The other macros are only | |
19 | ### really useful within this body. | |
20 | ### | |
21 | ### `mdw_PROG' expands, in the shell, to the transformed name of the | |
22 | ### program PROG. | |
23 | ### | |
24 | ### `mdw_PATH' expands, in the shell, to the recursive expansion of PATH, | |
25 | ### which should be a string containing parameter expansions. | |
26 | ### | |
27 | ### `mdw_DEFINE_PROG' is a convenience macro which defines the preprocessor | |
28 | ### SYMBOL to the result of `mdw_PROG(PROG)'; similarly `mdw_DEFINE_PATH' | |
29 | ### defines SYMBOL to the result of `mdw_PATH(PATH)'. | |
