## 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.

# Note, the powerpc-eabi build depends on sim occurring before gdb in order to
# know that we are building the simulator.

## All tools belong in one of the four categories, and are assigned above
## We assign ${configdirs} this way to remove all embedded newlines.  This

## ${configdirs} is directories we build using the host tools.
## ${target_configdirs} is directories we build using the target tools.
