Now you've tried almost all the details of the Dotfile Generator. Left are only a few odds and ends. So here they come in a somewhat random order. Write the following things on a new page, in a new file.
Use the -font option to the tk widget button and
label, with font
-adobe-*-*-*-*-*-$size-*-*-*-*-*-*-*.
The function
which creates the scale has to be in a file by itself, and this file
has to be included with the command source.
Now you should have tried all the things which the Dotfile Generator is capable of. If you should release the module, you only need to create a file called info, containing one line, which will be displayed when the user types dotfile without any arguments.
