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

### To add a new directory to the tree, first choose whether it is a target
### or a host dependent tool. Then put it into the appropriate list
### (library or tools, host or target), doing a dependency sort. For
### example, gdb requires that byacc (or bison) be built first, so it is in
### the ${host_tools} list after byacc and bison.

## These two lists are of directories that are to be removed from the
## ${configdirs} list for either cross-compilations or for native-
## compilations. For example, it doesn't make that much sense to
## cross-compile Emacs, nor is it terribly useful to compile xiberty in
## a native environment.
