<h2>14.2: Archiving Old Versions</h2>
Gri, like other complex programs, sometimes changes in such a way as to
break old scripts. This is less so of changes since about 1998 or so,
since the syntax became pretty firm about that time.
<p>
Still, disk costs are so cheap that you would be well-advised to keep a
backup version of Gri, whenever you update. This is pretty simple; you
need to keep a copy of the executable and the library file, and you need
to write a tiny shellscript that calls this particular executable with
this particular library file. For example, you might do the following
<p>
<TABLE SUMMARY="Example" BORDER="0" BGCOLOR="#efefef" WIDTH="100%">
<TR>
<TD>
<PRE>
<font color="#82140F">
mkdir -m 755 -p /usr/local/share/gri/2.12.26
cp /usr/bin/gri /usr/local/share/gri/2.12.26
cp /usr/share/gri/gri.cmd /usr/local/share/gri/2.12.26
</font></PRE>
</TD>
</TR>
</TABLE>
<p>
and then create a shellscript called
`<font color="#82140F"><samp>/usr/local/bin/gri-2.12.26</samp></font>' containing
<p>
<TABLE SUMMARY="Example" BORDER="0" BGCOLOR="#efefef" WIDTH="100%">
<TR>
<TD>
<PRE>
<font color="#82140F">
#!/usr/bin/sh
/usr/local/share/gri/2.12.26/gri \
-directory /usr/local/share/gri/2.12.26 \
"$@"
</font></PRE>
</TD>
</TR>
</TABLE>
<p>
to invoke this version of Gri.
<p>
To be able to access this old version of gri from within the Emacs
gri-mode, you would reset the Emacs variable `<font color="#82140F"><code>gri*directory-tree</code></font>'
like so in the file `<font color="#82140F"><samp>~/.emacs</samp></font>'
(see <a href="InstallingGriMode.html#Step2">Step 2</a> in
see <a href="InstallingGriMode.html#Installinggri-mode.el">Installing gri-mode.el</a>)
<p>
<TABLE SUMMARY="Example" BORDER="0" BGCOLOR="#efefef" WIDTH="100%">
<TR>
<TD>
<PRE>
<font color="#82140F">
(setq gri*directory-tree
'("/usr/local/share/gri/" "/usr/share/gri/"))
</font></PRE>
</TD>
</TR>
</TABLE>
