| 9 | dnl Arguments: CODE = shell script code to execute | |
| 10 | dnl | |
| 11 | dnl Use: Fixes up various variables so that pathname defines can be | |
| 12 | dnl defined. Within CODE, you may use the following macros: | |
| 13 | dnl | |
| 14 | dnl mdw_PROG(NAME) Transformed program name | |
| 15 | dnl | |
| 16 | dnl mdw_PATH(PATH) Expanded path (may contain variables) | |
| 17 | dnl | |
| 18 | dnl mdw_DEFINE_PROG(SYMBOL, PROG) | |
| 19 | dnl Define a symbol as a transformed | |
| 20 | dnl program name. | |
| 21 | dnl | |
| 22 | dnl mdw_DEFINE_PATH(SYMBOL, NAME) | |
| 23 | dnl Define a symbol as an expanded path | |
