Cross Tools in the Cygnus Tree

   The Cygnus tree is used for various packages including gdb, the GNU
binutils, and egcs.  It is also, of course, used for Cygnus releases.
   In the Cygnus tree, the top level `configure' script uses the old
Cygnus configure system, not autoconf.  The top level `Makefile.in' is
written to build packages based on what is in the source tree, and
supports building a large number of tools in a single
`configure'/`make' step.
   The Cygnus tree may be configured with a `--target' option.  The
`--target' option applies recursively to every subdirectory, and
permits building an entire set of cross tools at once.
