+// Also browsing the pages with "man" is obviously out of mind

+// Embedding multiple interpreters isn't that hard (after you
+// have read perlembed) but to start passing parameters
+// around you have to read at least perlembed, perlguts, perlxs,..
+// take a look at the perlinternals and have a good trip
+// around the web to find some examples for the functions

+// the perl values, but well ...
