Free Hero Mesh

* Message trace menu to enable/disable
* Bugs
  * Figure out why the $SeekerCloser class doesn't seem to work properly
  * Level 232 of SUPERHRO puzzle set (the Lava shouldn't expand? why?)
  * Animation stopping unexpectedly (until a key is pushed)
* Display solution comments/timestamp
* VCR mode
* Command-line switch for batch export levels
* SQL
  * Implement the GROUP column in the CLASSES table
  * Allow multiple SQL statements in one binding
* Fonts/text
  * More code pages
  * Large fonts (possibly: width 8 or 16, height 8-32)
  * Multibyte encodings (e.g. EUC-JP)

-f
  Only flush the user cache and then terminate.

-h
  Disable portable mode; always use the HOME environment variable to find
  the configuration and database files.

-i
  Batch import levels. Accepts the level import format (see export.doc)
  from stdin. It will not overwrite existing levels unless the existing
  level is blank, in which case it will overwrite it.

-n
  Create a new puzzle set. The .xclass and .class files should already
  exist; the .level and .solution files should not already exist, and will
  be created with minimal data.

-p
  Start the picture editor.

  solution; if at least one command like this is present then it will
  overwrite the existing solution when this level is saved. (Note: This
  does not automatically verify the solution; it only records it.)
  (Currently, this line is implemented only for import, and not for
  export. Later an option might be added to do this on export, too.)
