</div>As for dependencies on byte code: we could consider using Cython instead<br>
of freeze (not sure whether Cython would build the bootstrap correctly;<br>
it may need to be fixed first). With that, we would get semi-readable<br>
source code, which should also play more nicely with hg diffs. On the<br>
down side, we would depend on Cython for evolving .<br></blockquote><div><br></div><div>We could also just store the raw source code and use that if we are all willing to pay the performance cost of parsing and compiling the code at every startup.</div>

As for the timestamp issue: I think we should add a target "make touch"<br>
or some such which checks whether the respective files are unmodified<br>
in the local clone, and if so, arranges to touch generated files that<br>
are older than their sources. If this is done by a plain shell script,<br>
one could also make this a post-update Mercurial hook.<br></blockquote><div><br></div><div>So like execute hg diff on the dependent files and if nothing changed then touch the auto-generated file w/ 'touch' to prevent future attempts to execute the target?</div>
