/*
 * NAME
 *	ps2pk - creates a PK font from a type1 PostScript font
 * SYNOPSIS:
 *	pk2pk [options] type1 [pkname]
 * DESCRIPTION
 *	This program renders a given type1 PostScript font at a given
 *	pointsize (default 10.0 points) and resolution (default 300dpi)
 *      into a TeX PK font.
 *
 *      To generate the PK font pk2ps needs a valid type1 fontname (for
 *      example Utopia-Regular.pfa) and its corresponding AFMfile
 *	(Utopia-Regular.afm). The program accepts both the MSDOS binary
 *	type1 format (Utopia-Regula.pfb) and its UNIX ASCII equivalent
 *	(Utopia-Regula.pfa). The resulting PK font does contain all
 *	characters for which the C-code is non negative. This can be
 *	overruled by specifying an explicit <encoding> via the -e<encoding>
 *	option. Character codes in AMF files are specified as integer values
 *	after the C, for example Utopia-Regular.afm provides:
 *	   C 251 ; WX 601 ; N germandbls ; B 22 -12 573 742 ;
 *	   C  -1 ; WX 380 ; N onesuperior ; B 81 272 307 680 ;
 *
 *	The `germandbls' has code 251 and `onesuperior' -1 which means
 *	that this character is not part of the default AdobeStandard-
 *	Encoding scheme. To get this `onesuperior' you have to add it to
 *	an encoding vector as described in the PostScript manuals. But of
 *	course it is better to use standard encodings, like the one provided
 *	with the new psfonts. This `TeXBase1Encoding' encoding does contain
 *	all names of characters as defined in the 256 character TeX fonts.
 *
 *	The location of files for ps2pk, since version 1.5, has been
 *	improved using PostScript resource databases. These databases
 *	can be created using Adobe's mkpsres(1) utility. On UNIX the
 *	default name is PSres.upr and can be found in directories like
 *	/usr/lib/DPS depending on the machine you are using. The
 *	following example of an UPR file contains three resources
 *	   PS-Resources-1.0
 *	   Encoding
 *	   FontAFM
 *	   FontOutline
 *	   .
 *	   //usr/local/tex/fonts/type1faces
 *	   Encoding
 *	   ECEncoding=EC.enc
 *	   .
 *	   FontAFM
 *	   Courier=ResidentFonts/Courier.pfa
 *	   .
 *	   FontOutline
 *	   Courier=ResidentFonts/Courier.afm
 *	   .
 *
 *	When this UPR is in the PSRESOURCEPATH ps2pk can make an EC encoded
 *	PK font for Courier with:
 *
 *	   ps2pk -eECEncoding Courier
 *
 *	It is also possible without the UPR file but then you have to
 *	set T1INPUTS to the directories containing the files you need,
 *	for example:
 *
 *	   setenv T1INPUTS /usr/local/tex/fonts/type1faces//
 *
 *	and to run ps2pk by providing the proper filenames:
 *
 *	   ps2pk -eEC.enc Courier.pfa
 *
 *	In both cases the result will be the PK font Courier10.300pk.
 *	
 *	PostScript resource databases eliminate the need for recursive
 *	directory search, this is done by mkpsres(1) instead. And all
 *	resources can be stored in one directory per computer keeping 
 *	maintenance easy. Another advantage is the mapping of internal
 *	PostScript names, which are case sensitive and not restricted to
 *	MSDOS limitations, to external platform dependant filenames in
 *	a very natural way. On a MSDOS computer psres.dpr (the equivalent
 *	of PSres.upr) could be:
 *	   PS-Resources-1.0
 *	   Encoding
 *	   FontAFM
 *	   FontOutline
 *	   .
 *	   Encoding
 *	   TeXBase1Encoding=c:\emtex\dvips\8r.enc
 *	   .
 *	   FontAFM
 *	   Courier=c:\psfonts\com_____.pfb
 *	   .
 *	   FontOutline
 *	   Courier=c:\psfonts\afm\com_____.afm
 *	   .
 *
 *	Given this psres.dpr resource database
 *
 *	   ps2pk -eTeXBase1Encoding Courier
 *
 *	will create Courier10.300pk. Unfortunately MSDOS will abbreviate
 *	this name to COURIER1.300. Mkpsres(1) is an improved version
 *	of Adobe's makepsres(1) that runs on UNIX and MSDOS. This program
 *	will treat PFB fonts and PFM fonts correctly and recognize
 *	filenames ending with ".enc" as encoding vectors.
 *
 *	If the name of <type1font> does not contain an explicit extension
 *	or directory separator it is considered as the name of a resource.
 *	Otherwise as a filename. You can not mix up resource names and file-
 *	names. Filenames must have an extension!
 *
 * OPTIONS AND ARGUMENTS
 *       -a<AFM>        The name of the AFM resource or file can be
 *			overruled with this option.
 *       -e<encoding>   The encoding scheme (default the encoding from the 
 *                      AFM file is used).
 *	 -E<extension>	The extension factor (real value, default 1.0).
 *	 -O		Create old checksums (for compatibility)
 *	 -P<pointsize>	The desired pointsize (real value, default 10.0
 *			points). PK fonts created with a value different
 *			to 10.0 will cause dvips warnings `dvips: Design
 *			size mismatch in font ...'.
 *	 -R<baseres>	The base resolution (integer value, default 300
 *			dpi). Only used for creating METAFONT compatible 
 *			identification strings in PK postamble.
 *	 -S<slant>	The slant (real value, default 0.0).
 *	 -X<xres>	The resolution (integer value) in the X direction 
 *			(default 300 dpi).
 *	 -Y<yres>	The resolution (integer value) in the Y direction 
 *			(defaults to the value of <xres>).
 *	 -d		Debug stat() calls during recursive path searching
 *	 -v		Verbose flag. (Tells what the program is doing.)
 *	
 *	 type1font	The name of the PostScript type 1 font. When no
 *                      explicit AFMfile is given via the -a option the
 *                      name of the AFMfile will be constructed from this
 *                      name by removing the extension (if supplied) and
 *                      adding ".afm". 
 *	 [pkname]	The name of the resulting PK font can be overruled
 *			with this name. The default name of the PK font is
 *			derived from the basename of the type1 font, the
 *			pointsize and <xres>. For example:
 *			   ps2pk -P17.28 Utopia-Regular
 *			will result in:
 *				Utopia-Regular17.300pk
 *
 * ENVIRONMENTS
 *
 *   PSRESOURCEPATH
 *	The path used for locating PS resource database files (PSres.upr
 *	on UNIX and psres.dpr on MSDOS). The default of the path will be
 *	shown by running ps2pk with the -v flag and a non-existant resource
 *	name.
 *
 *   T1INPUTS
 *	The path used for locating PS type1 fonts, their AFM files and
 *	encoding vectors. Path may contain '//' (UNIX) or '!!' (MSDOS) to
 *	force ps2pk to look into subdirectories. Using PSRESOURCEPATH
 *	instead of T1INPUTS avoids recursion. The default of the path will
 *	be shown by running ps2pk with the -v flag and a non-existant
 *	filename.
 *	
 * ACKNOWLEDGEMENTS
 *	This program uses the type1 hinting and rendering software IBM 
 *	has donated to the X-consortium.
 *
 *      Since version 1.5 the lookup of PS resources as described in
 *      `Programming the Display PostScript System with X (Appendix A:
 *      Locating PostScript Resources)' from Adobe Systems is used.
