: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.
