In (re?)examining the Apocalypses, I've found something that confuses me a
bit. A2 refers to C as a "pseudopackage" and says:
__LINE__ becomes MY.line
__FILE__ " MY.file
There is also Apocalypsal reference to C<%MY> as a name for the current
lexical symbol table.

Now that we've got docs and specs for many of the other VM systems
out there, it's time to see about writing code to execute them. There
are three basic things we need here for each.
1) A bytecode loading module. This takes on-disk non-native bytecode
and turns it into parrot bytecode. At the

I would like to humbly submit a perl script designed to dig through the
Parrot directory tree, locate POD in likely _and_ unlikely places, and
generate a tree of HTML pages into a new subdirectory. Includes a top-level
index. Run it from the top-level parrot directory with no arguments. Start

We don't have a standard, at least until now.
