+AST
+===
+
+This is the AT&amp;T Software Technology (AST) toolkit from AT&amp;T Research.
+It includes many tools and libraries, like KSH, NMAKE, SFIO, VMALLOC, VCODEX,
+etc. It also includes more efficient replacements for a lot of the POSIX tools.
+It was designed to be portable across many UNIX systems and also works
+under UWIN on Microsoft Windows (see UWIN repo on GitHub under att/uwin).
+
+This software is used to build itself, using NMAKE.
+After cloning this repo, cd to the top directory of it and run:
+
+./bin/package make
+
+Almost all the tools in this package (including the bin/package script are
+self-documenting; run <tool> --man (or --html) for the man page for the tool.
+
+(If you were used to the old AST packaging mechanism, on www.research.att.com,
+this repo is equivalent to downloading the INIT and ast-open packages and
+running: ./bin/package read on them).

+[+DESCRIPTION?\bexecrate\b runs \acommand\a after checking the \afile\a
+	operands for standard semantics with respect to \bwin32\b \b.exe\b
+	suffix conventions. This command is only needed on \bwin32\b
+	systems that inconsistently handle \b.exe\b across library and
+	command interfaces. \acommand\a may be one of \bcat\b(1), \bchmod\b(1),
+	\bcmp\b(1), \bcp\b(1), \bln\b(1), \bmv\b(1), or \brm\b(1).
+	Only the 2 argument forms of \bcp\b, \bln\b and \bmv\b are handled.
+	Unsupported commands and commands requiring no change are
+	silently executed.]
+[+?With no arguments \bexecrate\b exits with status 0 if the current system
+	is \b.exe\b challenged, 1 if the current system is normal.]
