+# It is advisable to support a few --enable/--disable options to let the
+# user select which libraries s/he really wants.

+# Subdirectories wishing to use multilib should put the following lines
+# in the "post-target" section of configure.in.

+# See librx/configure.in in the libg++ distribution for an example of how
+# to handle autoconf'd libraries.
+#
+# Things are complicated because 6 separate cases must be handled:
+# 2 (native, cross) x 3 (absolute-path, relative-not-dot, dot) = 6.
+#
+# srcdir=. is special.  It must handle make programs that don't handle VPATH.
+# To implement this, a symlink tree is built for each library and for each
+# multilib subdir.
+#
+# The build tree is layed out as
+#
+# ./
+#   libg++
+#   newlib
+#   m68020/
+#          libg++
+#          newlib
+#          m68881/
+#                 libg++
+#                 newlib
+#
+# The nice feature about this arrangement is that inter-library references
+# in the build tree work without having to care where you are.  Note that
+# inter-library references also work in the source tree because symlink trees
+# are built when srcdir=.
+#
+# Unfortunately, trying to access the libraries in the build tree requires
+# the user to manually choose which library to use as GCC won't be able to
+# find the right one.  This is viewed as the lesser of two evils.
+#
+# Configure variables:
+# ${with_target_subdir} = "." for native, or ${target_alias} for cross.
+# Set by top level Makefile.
+# ${with_multisrctop} = how many levels of multilibs there are in the source
+# tree.  It exists to handle the case of configuring in the source tree:
+# ${srcdir} is not constant.
+# ${with_multisubdir} = name of multilib subdirectory (eg: m68020/m68881).
+#
+# Makefile variables:
+# MULTISRCTOP = number of multilib levels in source tree (+1 if cross)
+# (FIXME: note that this is different than ${with_multisrctop}.  Check out.).
+# MULTIBUILDTOP = number of multilib levels in build tree
+# MULTIDIRS = list of multilib subdirs (eg: m68000 m68020 ...)
+# (only defined in each library's main Makefile).
+# MULTISUBDIR = installed subdirectory name with leading '/' (eg: /m68000)
+# (only defined in each multilib subdir).
+
+# FIXME: Multilib is currently disabled by default for everything other than
+# newlib.  It is up to each target to turn on multilib support for the other
+# libraries as desired.
+
+# We have to handle being invoked by both Cygnus configure and Autoconf.
+#
+# Cygnus configure incoming variables:
+# srcdir, subdir, host, arguments
+#
+# Autoconf incoming variables:
+# srcdir, host, ac_configure_args
+#
+# We *could* figure srcdir and host out, but we'd have to do work that

+   The basic API is described in the README file.
+
+   The raw API is designed to bypass some of the argument packing
+   and unpacking on architectures for which it can be avoided.
+
+   The closure API allows interpreted functions to be packaged up
+   inside a C function pointer, so that they can be called as C functions,
+   with no understanding on the client side that they are interpreted.
+   It can also be used in other cases in which it is necessary to package
+   up a user specified parameter and a function pointer as a single
+   function pointer.
+
+   The closure API must be implemented in order to get its functionality,
+   e.g. for use by gij.  Routines are provided to emulate the raw API
+   if the underlying platform doesn't allow faster implementation.
+
+   More details on the raw and cloure API can be found in:
+
+   http://sourceware.cygnus.com/ml/java-discuss/1999-q3/msg00138.html
