| 3 | ## This file is a shell script fragment that supplies the information |
| 4 | ## necessary to tailor a template configure script into the configure |
| 5 | ## script appropriate for this directory. For more information, check |
| 6 | ## any existing configure script. |
| 7 | |
| 8 | ## Be warned, there are two types of configure.in files. There are those |
| 9 | ## used by Autoconf, which are macros which are expanded into a configure |
| 10 | ## script by autoconf. The other sort, of which this is one, is executed |
| 11 | ## by Cygnus configure. |
| 12 | |
| 13 | ## For more information on these two systems, check out the documentation |
| 14 | ## for 'Autoconf' (autoconf.texi) and 'Configure' (configure.texi). |

| 19 | ### or a host dependent tool. Then put it into the appropriate list |
| 20 | ### (library or tools, host or target), doing a dependency sort. For |
| 21 | ### example, gdb requires that byacc (or bison) be built first, so it is in |
| 22 | ### the ${host_tools} list after byacc and bison. |
