[Therion] metapost input file

[Andrew Atkinson]

My layouts for my areas has become difficult to manage, especially all
the metapost.

input file works in metapost, but requires the full path, is there a way
to find the path of the file that you are in and us that as a base. We
use version control so different machines have different file paths, so
really want to avoid this.

At the moment I have make a different file for my symbols and in each
file have to have a layout/endlayout and code metapost/endcode, then in
the master file I have to input outside the layout and then copy the
layout for each file, which works but it would be so much nicer to just
have

input symbol.mp inside the one code metapost/ endcode

thanks
