| 12 | dnl SYNOPSIS | |
| 13 | dnl | |
| 14 | dnl AX_WITH_PROG([VARIABLE],[program],[VALUE-IF-NOT-FOUND],[PATH]) | |
| 15 | dnl | |
| 16 | dnl DESCRIPTION | |
| 17 | dnl | |
| 18 | dnl Locates an installed program binary, placing the result in the precious | |
| 19 | dnl variable VARIABLE. Accepts a present VARIABLE, then --with-program, and | |
| 20 | dnl failing that searches for program in the given path (which defaults to | |
| 21 | dnl the system path). If program is found, VARIABLE is set to the full path | |
| 22 | dnl of the binary; if it is not found VARIABLE is set to VALUE-IF-NOT-FOUND | |
| 23 | dnl if provided, unchanged otherwise. | |
| 24 | dnl | |
| 25 | dnl A typical example could be the following one: | |
| 26 | dnl | |
| 27 | dnl AX_WITH_PROG(PERL,perl) | |
| 28 | dnl | |
| 29 | dnl NOTE: This macro is based upon the original AX_WITH_PYTHON macro from | |
| 30 | dnl Dustin J. Mitchell <dustin@cs.uchicago.edu>. | |
