-Random notes about the autoconfing of AST
-
-Initial version imported from a tarball supplied by DSB.  The tarball
-contained David's RCS repository plus the development directory (dev/)
-and the `reference' directory (ref/) which contains a checkout of the
-RCS repository.  The development directory contains working versions
-of the files in the reference directory, plus miscellaneous test files
-and notes, plus copies of sdt.tar.Z (the RCS wrapper which has long
-been used for AST development) and sst_source.tar.Z (the documentation
-builder).
-
-The RCS repository was dropped into the CVS repository on 14 November
-2003, and tagged with ast-3-1-0-import.  After thinking a bit about
-tagging policies (and writing these up on the wiki and posting to the
-stardev group), I tagged this same point as
-bp-dev-nxg-20031121-autoconfing and created a branch
-dev-nxg-20031121-autoconfing (21 November -- busy week since the
-14th...).  That's the one I'll work on.
-
-I've created configure.ac, and I've developed the build system using
-reasonably current versions of the autotools (namely autoconf-2.57,
-automake versions 1.6.3 or 1.7.5, and libtool versions 1.4.2 or 1.5).
-There's no point jumping through hoops to use random obsolete versions
-(reading old documentation, and trying to keep things forwards
-compatible, untestably) simply because they're installed on RH7.3.  If
-anyone plans to install these newer versions, I recall that autoconf,
-libtool, automake was the order that worked (it matters), and you need
-to install GNU m4 first on Solaris or Alpha
-
-Created starlink.m4, which includes macro STAR_FACILITY_CODE which
-facilitates declaring the `err' facility code which has been allocated
-to this library.  This also AC_SUBSTs the variable ERR_FACILITY_CODE,
-and I've moved ast_err.msg and error.h to the corresponding .in files,
-modified them to have that code inserted, and put them in
-AC_CONFIG_FILES.  This file should be moved to a central location when
-I work out where such a central location should be.  At that point,
-./bootstrap should be edited to contain that location.
-
-The two files in grp.make's F_ROUTINES group, object.f and frame.f,
-don't appear to be used anywhere.  I've omitted them in Makefile.am
-
-
-Building AST
-------------
-
-To build AST directly from the repository, you need reasonably current
-versions of the autotools (as noted above).  If anyone plans to
-install these newer versions, I recall that autoconf, libtool,
-automake was the order that worked (it matters), and you need to
-install GNU m4 first on Solaris or Alpha.
-
-Recall the discussion we had on stardev about autotools and generated
-files.  I have now checked in the generated files configure,
-config.h.in and Makefile.in.  Later, I'll either add the fixes I added
-to autoastrom to make the `missing' script work, or see if there's a
-more supported way to do that.  With those fixes and additions, it
-_will_not_matter_ which autotools versions you have, as long as you
-don't have to alter Makefile.am or configure.ac, and in any case it
-the autotools are completely unneeded for building from the
-distribution tarball.
-
-To build from the repository, do
-
-    ./bootstrap
-    ./configure
-    make
-
-
-Conventions and facilities so far
----------------------------------
-
-The version number is set in the AC_INIT line in configure.ac, and
-propagated from there to the locations where it's needed.
-
-The string @STAR_BOILERPLATE@ must be in Makefile.{am,in}.  All this
-does at present is include boilerplate for calling messgen _if_
-STAR_FACILITY_CODE is present (which it is, for AST).
-
-configure.ac should have STAR_DEFAULTS near the beginning (sets the
-default installation location to be /star rather than GNU default
-/usr/local, ensures that the STARLINK environment variable is set).
-
-STAR_FACILITY_CODE declares the error-reporting system facility code
-which has been allocated to this library.
-
-
-Modifications to AST files
---------------------------
-
-ast_err.msg is now created from ast_err.msg.in, and has the facility
-code declared in STAR_FACILITY_CODE edited into it at that point.
-Same for error.h and error.h.in.
-
-ast_cpp generated from ast_cpp.in with the CC edited in
-
-makeh now calls ast_cpp through /bin/sh (avoids having to worry about
-execute bits)
-
-Versioning: The version number (as mentioned above, set in
-configure.ac) is now substituted into version.h.in, broken into
-major.minor-release, and version.h is included in ast.h.  File
-object.c now includes version.h to implement the astVersion_
-function.  AST_MAJOR_VERS and co removed from makeh (since they're now
-included in ast.h inside version.h).
