Free Hero Mesh

** Why is there both Busy and UserSignal flags even though both flags do
the same thing?

 It is because Everett Kaser designed the MESH engine that way, but I
 don't know why it was designed that way. If you do not like to have
 both flags, then you do not have to use both.

** What is the MIME type and UTI for Free Hero Mesh?

 None is officially assigned, but unofficially, a composite puzzle set
 can use the following MIME type:

 application/freeheromesh.composite+hamarc

 Optional parameters for this MIME type are "codepage" which is a IBM
 code page number, and "version" which is the version of Free Hero Mesh
 (same as the numbers of the {version} macro). Both are optional.

 MIME types for the other file formats are not defined.

 The UTI for a Free Hero Mesh composite puzzle set file is:

 org.zzo38computer.freeheromesh.composite

 This UTI conforms to the following other UTIs:

 com.hamsterrepublic.lumped
 public.data

=== Code page numbers ===

Code page numbers are assigned according to the following:

* Code page numbers are 16-bit numbers. Numbers 0, 65534, and 65535 are
not used; they are reserved for internal use of the software.

* IBM and Microsoft code page numbers can be used. (Mostly, only IBM
code page numbers should be used, but in some cases (described below)
Microsoft code page numbers might be applicable.)

* If IBM and Microsoft use the same code page number for a different
character set, or if they use different code page numbers for the same
character set/encoding, then IBM takes precedence. However, if Microsoft
uses the code page number for a strict superset of IBM's definition,
then Microsoft's definition will be used.

* Extensions of FreeDOS are used if they do not conflict with IBM and
are not already present as official IBM code pages.

* The areas designated as private use areas by IBM (57344-61439 and
65280-65533) may be defined in future by myself (or others, with my
approval). Some ranges may also later be reserved as user-defined or
application-specific areas.

Note that not all of the code page numbers according to the above are
actually used in Free Hero Mesh; Free Hero Mesh only uses ASCII-based
code pages with 8-bit characters (although the implementation may be
improved in future to allow multibyte code pages, but currently it
doesn't). The full set of code page numbers may still be useful for
other applications, though.


=== List of code page numbers ===

In the below list, "=" means that it is already included in the provided
codepage.har file, and "-" means it isn't included (it might or might not
be included in future).
