Hi Sander,

I have written there is "no need to modify the rule file", I haven't 
written "there is no need for a rule file". ;)

There is generic code what has to be done in each stage. If you do not provide 
your own stage code in your rule file, the generic code will be used instead. 
For (perfect) autotoolized packages the generic stage code can be used.

To forward special options to the configure stage you just have to provide the 
<yourpackage-name>_CONF_OPT variable. But no code. The generic code uses the 
*_CONF_OPT content automagically.

Dependencies are handled inside the *.in files via "select". If you enable a 
package and this package needs another package, the enabled package must 
select the package it depends on. PTXdist also uses these "select" statements 
to define the build order of the packages.
