Subject: Re: eRuby and erb

The embedding techniques just make it slightely more
simple. Its annoying having to write
#!/usr/local/bin/ruby at the beginning of every file.
The way I have done it since i've been using php.

Include:
-template class
-dba class
-logic classes
-init objects
-get objects to get data from db
-pass that data in strings to template object.
-output

I guess i never thought about doing it without
embedding but now that i do think about it its not
really necessary. I'm porting the code over from
PHPLibs template class to ruby. I'll have to modify it
a bit so I can use it in a plain cgi environment. btw
if anyone is interested in using it once its done just
send me an email and i'll let you know when im done.

Cheers,
Billy
