Detailed Description
       Support for m17n library users to debug their programs.

       The m17n library provides the following facilities to support the library users to debug their programs.

       o Environment variables to control printing of various information to stderr.
	 o MDEBUG_INIT -- If set to 1, print information about the library initialization on the call of M17N_INIT().
	 o MDEBUG_FINI -- If set to 1, print counts of objects that are not yet freed on the call of M17N_FINI().
	 o MDEBUG_CHARSET -- If set to 1, print information about charsets being loaded from the m17n database.
	 o MDEBUG_CODING -- If set to 1, print information about coding systems being loaded from the m17n database.
	 o MDEBUG_DATABASE -- If set to 1, print information about data being loaded from the m17n database.
	 o MDEBUG_FONT -- If set to 1, print information about fonts being selected and opened.
	 o MDEBUG_FLT -- If set to 1, 2, or 3, print information about which command of Font Layout Table are being executed. The bigger number
	   prints the more detailed information.
	 o MDEBUG_INPUT -- If set to 1, print information about how an input method is running.
	 o MDEBUG_ALL -- Setting this variable to 1 is equivalent to setting all the above variables to 1.
	 o MDEBUG_OUTPUT_FILE -- If set to a file name, the above debugging information is appended to the file. If set to 'stdout', the
	   information is printed to stdout.
       o Functions to print various objects in a human readable way. See the documentation of mdebug_dump_XXXX() functions.
       o The hook function called on an error. See the documentation of mdebug_hook().

mfontset_modify_entry(3m17n)					 The m17n Library				      mfontset_modify_entry(3m17n)

NAME

       mfontset_modify_entry - Modify the contents of a fontset.

SYNOPSIS

       int mfontset_modify_entry (MFontset * fontset, MSymbol script, MSymbol language, MSymbol charset, MFont * spec, MSymbol layouter_name, int
       how)

DESCRIPTION

       Modify the contents of a fontset. The mfontset_modify_entry() function associates, in fontset fontset, a copy of font with the script /
       language pair or with charset.

       Each font in a fontset is associated with a particular script/language pair, with a particular charset, or with the symbol Mnil.  The fonts
       that are associated with the same item make a group.

       If script is not Mnil, it must be a symbol identifying a script. In this case, language is either a symbol identifying a language or Mnil,
       and font is associated with the script / language pair.

       If charset is not Mnil, it must be a symbol representing a charset object. In this case, font is associated with that charset.

       If both script and charset are not Mnil, two copies of font are created. Then one is associated with the script / language pair and the
       other with that charset.

       If both script and charset are Mnil, font is associated with Mnil.  This kind of fonts are called fallback fonts.

       The argument how specifies the priority of font.  If how is positive, font has the highest priority in the group of fonts that are
       associated with the same item. If how is negative, font has the lowest priority. If how is zero, font becomes the only available font for
       the associated item; all the other fonts are removed from the group.

       If layouter_name is not Mnil, it must be a symbol representing a mdbFLT (font layout table). In that case, if font is selected for drawing
       an M-text, that font layout table is used to generate a glyph code sequence from a character sequence.

RETURN VALUE

	   If the operation was successful, mfontset_modify_entry() returns 0. Otherwise it returns -1 and assigns an error code to the external
	   variable merror_code.

ERRORS

	   MERROR_SYMBOL
