+)abbrev package SPADPRSR SpadParser
+++ Author: Gabriel Dos Reis
+++ Date Created: October 10, 2006
+++ Date Last Updated: November 12, 2007
+++ Description:  This package provides a simple Spad algebra parser.
+++ Related Constructors: Syntax.
+++ See Also: Syntax.
+SpadParser(): Public == Private where
+  Public ==> with
+    parse: String -> List Syntax
+      ++ parse(f) parses the source file f (supposedly containing
+      ++ Spad algebras) and returns a List Syntax.  The filename f
+      ++ is supposed to have the proper extension.  Note that this
+      ++ function has the side effect of executing any system command
+      ++ contained in the file f, even if it might not be meaningful.
+
+  Private ==> add
+    parse f ==
+      parseSpadFile(f)$Lisp : List(Syntax)
