-\begin{verbatim}
-This file contains the BOOT code for the Axiom system command
-and synonym processing facility. The code for )trace is in the file
-TRACE BOOT. The list of system commands is $SYSCOMMANDS which is
-initialized in SETQ LISP.
-
-\end{verbatim}
-
-\section{Filenames change}
-
-It appears that probe-file is now case-sensitive. In order to get around
-this we include the file extensions in both upper and lower case in the
-search lists. Lower case names are preferred.
-
-\section{handleNoParseCommands}
-
-The system commands given by the global variable
-[[|$noParseCommands|]]\cite{1} require essentially no
-preprocessing/parsing of their arguments. Here we dispatch the
-functions which implement these commands.
-
-There are four standard commands which receive arguments -- [[lisp]],
-[[synonym]], [[system]] and [[boot]]. There are five standard commands
-which do not receive arguments -- [[quit]], [[fin]], [[pquit]],
-[[credits]] and [[copyright]]. As these commands do not necessarily
-exhaust those mentioned in [[|$noParseCommands|]], we provide a
-generic dispatch based on two conventions: commands which do not
-require an argument name themselves, those which do have their names
-prefixed by [[np]].
-
-<<handleNoParseCommands>>=
-handleNoParseCommands(unab, string) ==
- string := stripSpaces string
- spaceIndex := SEARCH('" ", string)
- unab = "lisp" =>
- if (null spaceIndex) then

-\section{TRUENAME change}
-This change was made to make the open source Axiom work with the
-new aldor compiler.z
-This used to read:
-\begin{verbatim}
- STRCONC(TRUENAME(STRCONC(GETENV('"AXIOM"),'"/compiler/bin/")),"axiomxl ", asharpArgs, '" ", namestring args)
-\end{verbatim}
-but now reads:
-<<remove TRUENAME>>=
- STRCONC(STRCONC(GETENV('"ALDORROOT"),'"/bin/"),_
- "aldor ", asharpArgs, '" ", namestring args)
-@
-Notice that we've introduced the [[ALDORROOT]] shell variable.
-This will have to be pushed down from the top level Makefile.
