This relenc package is released under the LaTeX Project Public License, version 1 or (at your option) any later version. ABSTRACT: What in my opinion is one of the most irritating limitations with the standard encodings used with LaTeX today is that they either have very few slots available for ligatures or offer no way in which LaTeX can make use all those accented character glyphs that fonts usually come equipped with. The relenc package makes it possible to get around this by introducing the concept of a relaxed encoding. Unlike normal encodings, relaxed encodings give the font designer (or whoever is setting up the font for use with LaTeX) a saying on what the author commands setting text from the fonts should really do to get their work done. This can be used to make more slots available for ligatures without more than marginally changing the visible result of any command. One such relaxed encoding is included with the relenc package: the T1R encoding. It behaves like T1 to the author, but allows the font designer to include some 60 ligatures in the font (T1 only allows seven). Note however that it is up to the font designer to decide how those 60 slots should be used, so any subset of them can just as well be used for accented letters. The package also comes with a font family called zcm, which exists only to provide an example of what can be done with the relenc package. This example can be viewed if you typeset the file reldemo.tex, but before you do that you need to have docstrip generate some other files. That will be done automatically if you run LaTeX on relenc.ins. The distribution of the package roughly consists of four logical parts: The first part is the package itself and its documentation, the second is the T1R encoding, the third is the zcm font family, and the fourth consists of files related to the distribution in general. The files in all four parts are listed and described below. All these files should be present in the distribution. If you recieve only some of these files from someone, then complain. The files in the fourth part are: README This file relenc.ins The docstrip installation script for the package and accompanying files. This script extracts files for parts one, two, and three from their respective documented source files. The files in the first part are: relenc.dtx The documented source file for the relenc package. relenc.tex The complete documentation. The appendices of this document even contain the documentation for the T1R encoding and zcm font family, but that text is located in the files t1renc.dtx and t1rzcm.fdd. 2sidedoc.sty A LaTeX2e package used when typesetting relenc.tex and relenc.dtx. See  below. The file in the second part is: t1renc.dtx The specification of the T1R encoding and the documented source for its encoding definition file. The files in the third part are: t1rzcm.fdd A short description of the zcm font family and the documented source for its font definition file. reldemo.tex A file that generates an example of what can be done with the relenc package. zcmr8d.tfm \ The actual font files for the zcm font family. zcmr8d.vf | PLEASE NOTE: These files are binary files and must be zcmr8d.vf2 | transferred as such. If TeX, while typesetting zcmr8d.vf3 \ reldemo.tex, stops and complains about "Bad metric (TFM) zcmra.tfm / file" then these files have most likely been damaged in zcmra.vf | some way. This sort of thing is usually caused by the zcmra.vf2 | files being FTPed as text files instead of binary zcmra.vf3 / files. ALSO NOTE: You only need four of these for any given TeX installation, but different installations need different subsets of them. See the documentation (typeset relenc.tex or t1rzcm.fdd) for more information. The files docstrip generate from the documented source files above are: relenc.sty This is the relenc package itself. t1renc.def This is the encoding definition file for the T1R encoding. t1rzcm.fd This is the font definition file for the zcm font family under the T1R encoding. ecsubzcm.sty This is a helper package, that may be useful for those who uses the T1R encoding but prefer not to have the zcm font family around. A simple installation: Files to put in some TeX inputs directory: relenc.sty t1renc.def t1rzcm.fd Files to put in some directory where TeX and DVI drivers looks for TeX font metric (TFM) files: zcmr8d.tfm zcmra.tfm Files to put in some directory where DVI drivers looks for virtual font (VF) files: zcmr8d.vf zcmra.vf  The usage of the 2sidedoc package here is merely to split some of my overlong macro names on more than one line, but I originally wrote it to get a better layout on files documented with the doc package when printing them in twoside mode. 2sidedoc sees to that the macro and environment names printed in the margin by the commands in doc always end up in the outer margin (instead of the left margin as with the naked doc package) when the class operates in twoside mode. One funny thing about the package is that it writes information in the aux file to help it figure out (for each piece of marginal material) which margin is the outer. Due to this you may have to typeset a document more than one time before the placing gets correct everywhere, but that is the same kind of problem you'll be used to get with incorrect page references, so we all know we can live with it. I intend to make a proper release of the 2sidedoc package sometime, but first I will have to do something about the placement of codeline numbers as well. As it turns out, the codeline numbers will assume the role of an optical axis on the page; marking the boundary between the body text and marginal material parts of the paper. This means that these codeline numbers will have to change side depending on whether the page is odd or even as well, just like the marginal material, and I haven't gotten round to implementing a mechanism for this yet. Still, there is no harm in using the package as it is. If you put its \usepackage somewhere after that of doc, then it will modify the doc macros that needs to be modified. You don't notice much of it however, unless you are typesetting with twosided printing active. Lars Hellstr�
