Recompile files

[Andrea Crotti]

I was wondering if I should recompile or not all my el files.  At the
moment I notice it takes quite long to boot at my emacs, and I guess
that would make it much faster.

But I also use the same configuration in different OS/versions.

So if I compile on one and then I copy the whole configuration on the
other I guess it might cause some troubles...

How do you handle this?  Should I keep everything compiled on each
machine and not transfer the *.elc files?

But then when I modify something I would again need to compile it
everywhere, and I would need some way to detect this automatically.

Someone has already solved this problem maybe?

Thanks
