I don't know how exactly works ProjectInfo but why not use it to set  
default values to tasks ?

Imagine the rdoc task requires a source parameter. If ProjectInfo  
contains rdoc[:source], it would be used by the reap task. Otherwise,  
reap would ask for the source option. (cf: Glue's configuration)

Yes this is a good idea.

Yes as project directory, a reap config parameter can be useful. I  
just hope it won't add too many lines of code.

Concerning Gem autoload. A quick google search showed me that you can  
tell a gem to autorequire a file. As I understood, you can build gems  
in a way that they will automatically require a gem when 'rubygem' is  
required. I don't know how it works with multiple versions of the  
same gem altrough. This means that Gems could autorequire rake tasks  
so that they are loaded in the namespace. You then could use the  
ObjectSpace browsing method to look for available tasks. Concerning  
standard ruby intalls, the RUBYOPT env variable could be used to  
attain the same effect. Or is there an autorequire feature also  
available in standard ruby libs ?
