+The programm KDVI is based on the dvi-previewer xdvik, See below. KDVI
+was written by Markku Hihnala with the help of many
+collaborators. Later KDVI became a plug-in to KViewShell and Stefan
+Kebekus re-implemented parts of the program. The current version of
+KDVI shares a substantial amount of code with xdvi, not not very much
+with the first versions of KDVI.

+
+AUTHORS OF xdvik
+================
+
+This program, xdvik, was modified by [email protected] from Paul Vojta's
+xdvi distribution for common path searching, GNU-style configuration,
+etc.  Send bug reports to [email protected], not to Paul.  See the
+README for more info.
+
+Here are the credits for the original xdvi program:
+
+This program is the combined work of many people, including but not restricted to:
+	Eric Cooper, CMU
+	Bob Scheifler, MIT LCS
+	Paal Kvamme, Norwegian Institute of Technology
+	H\aa vard Eidnes, Norwegian Institute of Technology
+	Mark Eichin, MIT SIPB
+	Paul Vojta, UC Berkeley
+	Jeffrey Lee, U of Toronto
+	Donald Richardson, Clarkson Univ.
+
+In addition to the various comp.sources.x archives, current versions
+of this program (the original xdvi, not xdvik) can also be obtained
+via anonymous ftp from the following location:
+
+	export.lcs.mit.edu	[18.30.0.212]	file contrib/xdvi.tar.Z
+To ease the load on expo, you may also check other X archives, for example:
+	gatekeeper.dec.com	[16.1.0.2]	file pub/X11/contrib/xdvi.shar.Z
+
+Paul Vojta is now the primary maintainer.

+ToDo-List for kdvi
+
+URGENT / URGENT BUGFIXING
+
+o improve performance and perceived performance (see also under 'highly desirable')
+
+o do not render the same PS code more than once if all pages have the same PS code
+o add "papersize" which does not display the margin
+o get rid of useless README.kdvi
+o Proper handling of the base-url
+o add "tt.dvi.gz" to the list of recent files, not "/tmp/kviews....."
+o If one presses PgDn for a while, kdvi spends minutes browsing through pages...
+
+HIGHLY DESIRABLE
+
+o Speedup, in particular for ghostscript and glyph enlarging.
+
+o Support papersize information given by the dvi-file on a page-by-page
+  basis.
+
+o asynchronous rendering of pages, so that browsing with pg up/down looks faster
+
+
+NOT SO URGENT
+
+o Internal printing using QPrinter
+o Magnifier window
+o Two page view
+o Support for even more TeX specials
+o more robust Error handling with throw/catch; no need to abort just because a PK-file is bad.

+/**
+ * This class represents the contents of a font encoding file,
+ * e.g. "8r.enc"
+ *
+ * Explanation of font encodings: TeX was designed to only use
+ * MetaFont fonts. A DVI file referres to a MetaFont font by giving an
+ * at-most-8-character name, such as 'cmr10'. The DVI previewer would
+ * then locate the associated PK font file (e.g. cmr10.600pk), load
+ * it, and retrieve the character shaped.
+ *
+ * Today TeX is also used to access Type1 and TrueType fonts, which it
+ * was never designed to do. As in the case of MetaFont font, the DVI
+ * file specifies the name of a font, e.g. 'rpbkd', and the DVI
+ * previewer finds the associated font file 'ubkd8a.pfb' by means of a
+ * map file (see fontMap.h). The font map file also specifies an
+ * encoding (e.g. '8r', to be found in a file '8r.enc'). Font
+ * encodings are necessary because TeX can only use the first 256
+ * characters of a font, while modern PostScript fonts often contain
+ * more.
+ *
+ * In a PostScript font, glyphs can often be accessed in two ways:
+ *
+ * (a) by an integer, the 'glyph index', which need not be
+ * positive. Glyph indices can be found in every font.
+ *
+ * (b) by the name of the glyph, such as 'A', 'plusminus' or
+ * 'ogonek'. Note: Not all fonts contain glyph names, and if a font
+ * contains glyph names, they are not always reliable.
+ *
+ * An encoding file is essentially a list of 256 names of glyphs that
+ * TeX wishes to use from a certain font. If the font contains more
+ * than 256 glyphs, TeX is still limited to use at most 256 glyphs. If
+ * more glyphs are required, TeX can probably use the same font under
+ * a different name and with a different encoding ---the map file
+ * (fontMap.h) can probably see to that.
+ *
+ * Summing up: this class contains 256 glyph names read from an
+ * encoding file during the construction of this class.
+ *
+ * @author Stefan Kebekus   <[email protected]>

+ * A font map file is part of the machinery that make it possible to

+ *
+ * Long time ago, when TeX was only used with MetaFont fonts, the DVI
+ * file would specify a font by giving an 8-character name, such as
+ * 'cmr10'. The DVI previewer would then locate the associated PK font
+ * file, load it, and retrieve the character shaped. Happy times, they

+ *
+ * Today TeX is also used to access Type1 and TrueType fonts, which do
+ * not fit well into the TeX naming scheme. Like in earlier times, the
+ * DVI file specifies the name of a font, e.g. 'rpbkd', but nowadays
+ * the DVI previewer cannot just go and find a file 'rpbkd.pk'. No,
+ * no. Instead, the DVI previewr needs to look up the meaning of
+ * 'rpbkd' in a map-file. There it finds that 'rpbkd' refers to a font
+ * called 'URWBookmanL-DemiBold', to be found under the file name
+ * 'ubkd8a.pfb' whose glyphs are to be encoded using the '8a' encoding
+ * file (see the header file 'fontEncoding.h' for more information
+ * about encodings)
+ *
+ * Such map files exists for all dvi output drivers that are part of
+ * the TeX distribution that is installed on your
+ * computer. Unfortunately, KDVI is not part of a TeX distribution,
+ * and therefore does not have its own map file. As a workaround, KDVI
+ * uses the map file of the program ps2pk which is similar to KDVI in
+ * that the ps2pk driver does not have built-in fonts, unlike the
+ * PostScript printers for which dvips is used.
