+/*
+ * {automake|configure} => {nmake|iffe} conversion support
+ *
+ * The first command line target overrides the default original source
+ * directory name $(MAKEFILE:D). The hard work is in the makefile using
+ * these assertions, since it must (manually) provide the nmake makefiles
+ * and config equivalent iffe scripts. The conversion makefile is typically
+ * named lib/package/PACKAGE.cvt in an ast package $PACKAGEROOT directory,
+ * and the conversion is run from the $PACKAGEROOT directory, e.g.:
+ *
+ *	nmake -I lib/package -f PACKAGE-VERSION/PACKAGE.cvt
+ *
+ * The conversion requires the ast nmake, pax and tw commands.
+ *
+ * After the conversion you will be liberated from ./configure, *.in,
+ * *.am, automake, autom4te, libtool, make depend, and makefile
+ * recursion ordering. You can build from $PACKAGEROOT using the ast
+ * package(1) (which sets up the { HOSTTYPE PATH VPATH } environment):
+ *
+ *	package make
+ *
+ * or cd into any arch/$HOSTTYPE/src subdirectory and rebuild that portion
+ * of the hierarchy with the ast nmake(1) (after setting PATH and VPATH):
+ *
+ *	nmake
+ *
+ * The conversion assertions are:
+ *
+ *	package :CONVERT: file ...
+ *
+ *	    files in the original source directory are copied
+ *	    and converted into the ./src and ./lib subdirectories 
+ *	    the default original source directory is ./original
+ *
+ *		package	package name
+ *		file	original source file that must exist
+ *
+ *	:OMIT: pattern
+ *
+ *	    files matching pattern are not copied into the converted
+ *	    directory
+ *
+ *		pattern	ksh pattern of files to omit
+ *
+ *	:COPY: from to [ file ... ]
+ *
+ *	    files in the from directory are copied to the to directory
+ *	    the action may contain :MOVE: exceptions to the copy
+ *

+ *			  . names the original directory
+ *			 .. names the 
+ *		to	converted subdirectory
+ *			  libNAME => src/lib/libNAME
+ *			     NAME => src/cmd/NAME
+ *		file	files or files in subdirectories to be copied;
+ *			explicit files are copied to the to directory;
+ *			if no files are specified then the from hierarchy
+ *			is recursively copied to the converted directory
+ *
+ *	:MOVE: to file ...
+ *
+ *	    :COPY: assertion exceptions placed in the assertion's action
+ *
+ *		to	files or subdirectory files are copied to this directory
+ *		file	file or files in subdirectories to be copied
+ *
+ *	:FILE: to file <<!
+ *	contents
+ *	!
+ *
+ *	    the :FILE: action is copied to the named file in the to directory

+ *	!
+ *
+ *	    the :EDIT: action is an ed(1) script applied to each file in the
+ *	    to directory after it has been copied from the original source

+ *	    that is applied to all files matching the file pattern during the
+ *	    copy from the original source directory; a file may be subject to

+
+:DESCRIPTION:
+	The AT&T Software Technology ast-ksh package from AT&T Research
+	contains ksh and support libraries. This is the minimal set of
+	components needed to build ksh.
+
+:DETAILS: cyg
+	:README:
+		This package installs a standalone ksh93 executable ksh93.exe
+		and its man page ksh93.1.  If /bin/ksh.exe does not exist then
+		these symlinks
+			/bin/ksh.exe => ksh93.exe
+			/usr/share/man/man1/ksh93.1 => ksh.1
+		are created.  This allows alternative ksh impelementations,
+		e.g., /bin/pdksh.exe, to be selected by changing the ksh.exe
+		and ksh.1 symbolic links.  In addition, ksh and ksh93 paths are
+		added to /etc/shells if not already present.
+		$()
+		Each builtin or special command accepts the --man and --html
+		options to list the man page on the standard error. The --???
+		option describes the self documenting options available to all
+		builtin and special commands.
+		$()
+		The stanadlone ksh is statically linked with the ast libcmd
+		library which provides several builtin versions of /bin
+		commands. "builtin | grep /opt/ast/bin" lists the libcmd
+		builtins on the standard output. /opt/ast/bin/FOO accesses
+		the FOO builtin, whether the /opt/ast/bin directory exists
+		or not. "builtin FOO" allows /opt/ast/bin/FOO to be accessed
+		as FOO, bypassing the $PATH setting. To enable all libcmd
+		builtins do one of the following:
+		  (a) create the directory /opt/ast/bin and the file
+		      /opt/ast/bin/.paths with this line
+		      	BUILTIN_LIB=.
+		      and place /opt/ast/bin before /bin and /usr/bin in $PATH
+		      (this will affect all ksh subshells and scripts)
+		  (b) run "builtin $( builtin | sed -e '/\//!d' -e 's,.*/,,' )"
+		      (this will affect only the current shell)
+		Some scripts may run significantly faster with libcmd builtins
+		enabled.
+		$()
+		The ast library checks the DOSPATHVARS environment variable
+		for variable path values to convert to and from native windows
+		format when cross-executing between cygwin and non-cygwin
+		programs. The value is a space separated list of environment
+		variables to convert. PATH is handled by cygwin so it is not
+		converted by the ast library.
+		$()
+		The astksh cygwin source package provides a bootstrap build
+		environment that is not suited for an edit/build/debug cycle.
+		If you want to explore and modify the source then you should
+		install the (non-cygwinized) ast-base package which includes
+		AT&T nmake. With ast-base you will also be able to regenerate
+		the astksh cygwin source and binary packages.
+		$()
+		For more information on ksh and other AT&T ast tools see
