Free Hero Mesh

read-only. Composite puzzle sets are probably best in this case since they
are always opened read-only. There is no need to restrict execution of any
file, or reading any installed file (even if the file is modified by the
system administrator).

Games: Debian policy has some specifications that are specific to game
programs. These probably apply normally to Free Hero Mesh. The set-group-id
mechanism is not needed; Free Hero Mesh does not share scores (it might be
added in future, but would be an optional feature, anyways). It is OK to
install binaries in /usr/games and man pages in /usr/share/man/man6 but
the "har" program (which should probably be a separate package) should be
installed in /usr/bin instead, probably.

X Window System: This is probably not applicable, because SDL is able to
use other video systems, although normally the X window system is used. If
the operating system doesn't use X window system, then the program should

if you have puzzle sets with valid solutions recorded. However, this only
tests the behaviour of the game engine, and not any other features. Also,
it only tests valid solutions, and not parts of the code that should result
in error messages (although this possibility might be added in future).


=== Game execution and user interface ===

You may use the existing implementations for user interfaces and will not
need to write a new implementation; but some ports might need a new user
interface; if it does, then the below notes may be helpful.

The exec.c and class.c files are the most important files, and can probably
be used with minor changes even if porting to different systems and/or user
interfaces. The other files could be omitted, but then those parts must be
rewritten (possibly in a different programming language); some parts of the
existing files could be copied if needed.


=== Character encoding ===

Free Hero Mesh does not and will not use Unicode. As of this writing, it
only supports single-byte character codes, although in future it is
intended that multi-byte codes (e.g. EUC-JP) might also be implemented.


=== Touch screen ===

A DOS version of Free Hero Mesh could additionally be changed to use an
internal clipboard, or an optional device driver for clipboard.

It may be desirable to implement support for importing and exporting PCX
and Dr.Halo picture formats directly, either built-in or using a separate
program that is included with it, in the DOS version.

DOS uses CRLF line endings instead of LF only like UNIX does. Free Hero
Mesh already can read class definition files with or without carriage
returns. The level import also can read with or without carriage returns.
However, exports do not add carriage returns.


=== Amiga ===

(TODO)


=== Microsoft Windows ===

The same consideration about line endings with DOS also applies to Windows.


=== Mac OS X ===
