|---|

|---|
| 9 | # DESCRIPTION |
|---|
| 10 | # |
|---|
| 11 | # Test for program options library from the Boost C++ libraries. The macro |
|---|
| 12 | # requires a preceding call to AX_BOOST_BASE. Further documentation is |
|---|
| 13 | # available at <http://randspringer.de/boost/index.html>. |
|---|
| 14 | # |
|---|
| 15 | # This macro calls: |
|---|
| 16 | # |
|---|
| 17 | # AC_SUBST(BOOST_PROGRAM_OPTIONS_LIB) |
|---|
| 18 | # |
|---|
| 19 | # And sets: |
|---|
| 20 | # |
|---|
| 21 | # HAVE_BOOST_PROGRAM_OPTIONS |
