I’m trying to build html documentation for ruby-1.9.1-p129.  
I have extracted source code and run command:  
rdoc19 -o /tmp/rdoc --inline-source --line-numbers -f html

But it use too much memory (\>2GB with swap) and I must kill process  
when it generated ~20MB of final html documentation.  
Can you, please, suggest how to solve this problem?

Thanks

Hmm. use the latest version of rdoc [what is rdoc19?]?  
I’ve run into this before, it does terminate eventually [for me], just  
takes awhile!

here’s online copies:

On my machine, the documentation is about 50 MB.
