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. | |

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. | |

13 | ## For more information on these two systems, check out the documentation |
14 | ## for 'Autoconf' (autoconf.texi) and 'Configure' (configure.texi). | |

18 | ### To add a new directory to the tree, first choose whether it is a target | |
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. | |
