| | 339 | dnl Test for the Boost C++ libraries of a particular version (or newer) |
| | 340 | dnl |
| | 341 | dnl If no path to the installed boost library is given the macro |
| | 342 | dnl searchs under /usr, /usr/local, and /opt, and evaluates the |
| | 343 | dnl $BOOST_ROOT environment variable. Further documentation is |
| | 344 | dnl available at <http://randspringer.de/boost/index.html>. |
