11:DESCRIPTION:
12	The AT&T Software Technology ast-ksh package from AT&T Research
13	contains ksh and support libraries. This is the minimal set of
14	components needed to build ksh.

16:DETAILS: cyg
17	:README:
18		This package installs a standalone ksh93 executable ksh93.exe
19		and its man page ksh93.1.  If /bin/ksh.exe does not exist then
20		these symlinks
21			/bin/ksh.exe => ksh93.exe
22			/usr/share/man/man1/ksh93.1 => ksh.1
23		are created.  This allows alternative ksh impelementations,
24		e.g., /bin/pdksh.exe, to be selected by changing the ksh.exe
25		and ksh.1 symbolic links.  In addition, ksh and ksh93 paths are
26		added to /etc/shells if not already present.
27		$()
28		Each builtin or special command accepts the --man and --html
29		options to list the man page on the standard error. The --???
30		option describes the self documenting options available to all
31		builtin and special commands.
32		$()
33		The stanadlone ksh is statically linked with the ast libcmd
34		library which provides several builtin versions of /bin
35		commands. "builtin | grep /opt/ast/bin" lists the libcmd
36		builtins on the standard output. /opt/ast/bin/FOO accesses
37		the FOO builtin, whether the /opt/ast/bin directory exists
38		or not. "builtin FOO" allows /opt/ast/bin/FOO to be accessed
39		as FOO, bypassing the $PATH setting. To enable all libcmd
40		builtins do one of the following:
41		  (a) create the directory /opt/ast/bin and the file
42		      /opt/ast/bin/.paths with this line
43		      	BUILTIN_LIB=.
44		      and place /opt/ast/bin before /bin and /usr/bin in $PATH
45		      (this will affect all ksh subshells and scripts)
46		  (b) run "builtin $( builtin | sed -e '/\//!d' -e 's,.*/,,' )"
47		      (this will affect only the current shell)
48		Some scripts may run significantly faster with libcmd builtins
49		enabled.
50		$()
51		The ast library checks the DOSPATHVARS environment variable
52		for variable path values to convert to and from native windows
53		format when cross-executing between cygwin and non-cygwin
54		programs. The value is a space separated list of environment
55		variables to convert. PATH is handled by cygwin so it is not
56		converted by the ast library.
57		$()
58		The astksh cygwin source package provides a bootstrap build
59		environment that is not suited for an edit/build/debug cycle.
60		If you want to explore and modify the source then you should
61		install the (non-cygwinized) ast-base package which includes
62		AT&T nmake. With ast-base you will also be able to regenerate
63		the astksh cygwin source and binary packages.
64		$()
