<p>NOTES:</p>
<ul class="simple">
<li><p>Commands that run external programs (e.g. systemctl) currently use
the <em>host</em>'s copy of that program, which may cause problems if there's a
big enough difference between the host and the image you're modifying.</p></li>
<li><p>The commands are not executed under a real chroot, so absolute symlinks
will point <em>outside</em> the inroot/outroot. Be careful with symlinks!</p></li>
</ul>
<p>ADDING NEW COMMANDS:</p>
<ul class="simple">
<li><p>Each template command is just a method of the LoraxTemplateRunner
object - so adding a new command is as easy as adding a new function.</p></li>
<li><p>Each function gets arguments that correspond to the rest of the tokens
on that line (after word splitting and brace expansion)</p></li>
<li><p>Commands should raise exceptions for errors - don't use sys.exit()</p></li>

<p>This class parses and executes Lorax templates. Sample usage:</p>
<blockquote>
<div><p># install a bunch of packages
runner = LoraxTemplateRunner(inroot=rundir, outroot=rundir, dbo=dnf_obj)
runner.run(&quot;install-packages.ltmpl&quot;)</p>
</div></blockquote>
<p>NOTES:</p>
<ul>
<li><p>Parsing procedure is roughly:
1. Mako template expansion (on the whole file)
2. For each line of the result,</p>
<blockquote>
<div><ol class="loweralpha simple">
<li><p>Whitespace splitting (using shlex.split())</p></li>
<li><p>Brace expansion (using brace_expand())</p></li>
<li><p>If the first token is the name of a function, call that function
with the rest of the line as arguments</p></li>
</ol>
</div></blockquote>
</li>
<li><p>Parsing and execution are <em>separate</em> passes - so you can't use the result
of a command in an %if statement (or any other control statements)!</p></li>
