How do I customize the export process?
Under the "Advanced" preferences, there is an option to specify a custom export command. This is a shell command through which you can pipe the MultiMarkdown source to generate your own output. This allows you have to have total control over the output process, but does require some knowledge of the command line and shell scripts.
For example, if you had a version of Markdown installed at
/usr/local/bin/markdown , you would put that in the
"Custom export" field. Then, when exporting, simply choose the
"Custom Export Document" option and tell Composer where to save
your file. It is your responsibility to be sure that your
shell script works properly, but we'll certainly help if there's a
problem with Composer.
