java based interpreter and regexes

| | + 15752 [decoux@mo lo] There are differences between perl5 and ruby for the regexp engine.
| | + 15759 [ser@ma s. er] Hm. I was comparing Ruby 1.6.4 against IBM's Java 1.3 on Linux.

15735 [elanthis@us ] I've run into a few issues in my project AweMUD in trying to embed Ruby in relation to compilation. I'm using automake/autoconf, but I can't find an easy way to detect/configure the settings for compiling in the Ruby library (library and include paths, basically).

+ 15749 [wayne.blair@] This is a fairly common practice when taking advantage of polymorphism.

Challenges of java interpreter
15754 [wayne.blair@] To create a java interpreter for ruby, ruby would ideally be coded in itself

| + 15761 [ser@ma s. er] C is pretty famous for (practically) bootstrapping itself this way.
