## 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 libraries are used by various programs built for the host environment
#

# these tools are built for the host environment

# The following either don't currently configure in a separate build
# or else don't build and install correctly from that directory:

# gnat-2.00
# ixpipe-1.0
# ixtrace-1.2
# libm-5.4
# libnix-0.7
#
# These should build and install from a separate build directory.
