[pacman-dev] How does pacman interact with a package's INSTALL script

[Xavier]

For the record, he first asked on the forums :
http://bbs.archlinux.org/viewtopic.php?id=34188
I answered but also said it was probably more appropriate to ask here.

After reading this part, I was wondering what some TODO meant, which
were added by Dan in this commit :
http://projects.archlinux.org/git/gitweb.cgi?p=pacman.git;a=commit;h=cd34ced4ada0bac8a370062fbc3cb58e3987cd33

+ /*TODO clean this code up, remove weird SCRIPTLET_START/DONE,
+ * (void*)atol call, etc. */

I found this code a bit weird at the beginning, but finally, I don't
really see how it could be improved so I'm curious.
