## This file is a shell script fragment that supplies the information
5
## necessary to tailor a template configure script into the configure
6
## script appropriate for this directory.  For more information, check
7
## any existing configure script.
8
 
9
## Be warned, there are two types of configure.in files.  There are those
10
## used by Autoconf, which are macros which are expanded into a configure
11
## script by autoconf.  The other sort, of which this is one, is executed
12
## by Cygnus configure.
13
 
14
## For more information on these two systems, check out the documentation
15
## for 'Autoconf' (autoconf.texi) and 'Configure' (configure.texi).

### To add a new directory to the tree, first choose whether it is a target
36
### or a host dependent tool.  Then put it into the appropriate list
37
### (library or tools, host or target), doing a dependency sort.  For
38
### example, gdb requires that byacc (or bison) be built first, so it is in
39
### the ${host_tools} list after byacc and bison.
