Hi, I suggest adding:

<metadata>
    <property name="mimetypes">text/x-amc-txt</property>
    <property name="line-comment-start">#</property>
  </metadata>

to the amc-txt.lang file.
The gedit text editor has a code comment plugin that uses this data so that a question can be easily commented out.

This way I can keep all questions in one file and comment out the ones I do not need for a certain test.
