Rewritten question. For my phd-project i need to quote screenplays. I would like to keep the screenplay layout in my thesis. I know there is the document class called screenplay.
Now i am wandering if it is generally possible to convert a document class into an "classic" environment, so that you can use all the useful stuff of one document class within another document class.
In my case I would like to write \begin{screenplay}...\end{screenplay} and include all the helpful devices from the screenplay document class within this environment. For example:
\begin{screenplay}
\fadein
\intslug[Tag]{Bantago Bay}
...
\end{screenplay}
screenplayclass isn't very complicated. The main thing you would need to do to adapt it to a package would be to remove all the titling and page layout stuff. So the core macros are from line 122 onwards, plus any of the lengths that are used in those commands (which are declared and set earlier in the code.). Do you feel comfortable around package code, or have you never looked inside one before? – Alan Munn Aug 21 '11 at 13:50
