	* src/ttfdump.c,
	  Makefile.in,
	  include/ttc.h,
	  include/ttf.h,
	  libttf/Makefile.in,
	  libttf/tabledir.c,
	  libttf/ttfread.c,
	  src/Makefile.in:

	Diffs from Nelson Beebe:

	  new target `check' for Makefile, `install' improved

	  #include <unistd.h> in ttf.h

	  ttfread.c: workaround for egcs bug

	  ttfdump.c: `int main' instead of `void main'
	             use of EXIT_SUCCESS and EXIT_FAILURE
	             added Strdup() since strdup() doesn't exist everywhere

	formatting of ttfdump.c

	* ttfdump : 
	Unrecoverable disaster had happened. The old developing version was
	destoried during Red Hat Linux upgrading (it is my fault :~~(. ).
	Resume to the public releease version.

	* font.c (ttfInitFont): The final layer of abstraction is complete.
	Application programs only need to do the fellowing things to use 
	True Type Font:
	  1. Load the font by calling ttfInitFont(char *font_filename)
	  2. choose a encoding scheme.
	  3. load the glyf by ttfLoadGlyphIndex or ttfLoadglyphCode
	  4. do anythings the application wants about the outline data
	     (i.e. rendering ,showing).
	  4. after all this, release the font by ttfFreeFont(TTFontPtr font).

	* gcache.c: The implementation of glyph cache is completed. Start to 
	add the final layer of TTFont abstraction.
	* glyf.c: It has been proved that av*.ttf is created by brain damaged
	programmers. Lots of LOCA entries point to End Of File.

	Benchmark: All Glyf data are loaded but not printed.

	* glyf.c: composite glyph added but not completed yet,does not works
	on av*.ttf any more but fine for others  (is it a bug in av*.ttf or 
	my fault ??)
	* glyf.c (ttfLoadGlyphIndex): removed the offset parameter
	and add the glyphOffset entry in TTFont structure,which contain
	the address of the start of glyf table, almost the same speed.

	* post.c : created
	add postscript information,format 2.0 ,2.5 not implemented yet

	* Release Version 0.4:
	Almost all required tables in True Type Font Specitication are
	implemented, except "post", "OS/2" and format 2,4,6 of "cmap".
	Composite glyph and instruction disassembler are not supported yet.
	Works fine on times.ttf,dftt-fs.ttf, unexpected EOF on avbbv.ttf,
	avov.ttf. (possible wrong ttf file)

	There are still some possible memory leak, clean then up when
	freezing stage.
