F. Beebe <beebe@math.utah.edu>.) + +This directory contains UNIX manual pages for TeXware and MFware. + +Here are some guidelines for writing UNIX manual page files, based on +the standards used by Sun Microsystems. The manual pages in this +directory have been revised to conform to these guidelines. + +*** The sections of a manual page are identified by these headings: + +.TH PROGRAM 1 "dd month yyyy" +.SH NAME +.SH SYNOPSIS +.SH DESCRIPTION +.SH OPTIONS +.SH ENVIRONMENT +.SH FILES +.SH "SEE ALSO" +.SH AUTHOR + +Additional sections may be supplied, but the above section order +should be preserved. If you are adding a new section, try to find +several examples in existing UNIX manual pages to justify the header +name you choose. + +To improve readability of the [nt]roff man page files in this +directory, each section header has been prefixed by a comment line of +the form +.\"===================================================================== + + +------------------------------------------------------------------------ + +*** The + +.TH PROGRAM 1 "dd month yyyy" + +line should be the first [nt]roff dotted command in the .man file, +other than comments, which begin with the 3-character sequence .\". + +The PROGRAM name should be spelled entirely in uppercase letters. + +The single character following PROGRAM is the manual page section, +generally 1 for user commands. Any character from the set [1-8nl] is +recognized by the UNIX man command, but the sections have specific +meanings (1=user commands, 2=system calls, 3=library routines, 4=special +files, 5=file formats and conventions, 6=games, 7=macro packages and +language conventions, 8=maintenance, l=local, and n=new). + +Historically, man page files were stored in /usr/man/man[1-8nl], with +local additions to /usr/man/manl. That approach offered no +subdivision of local additions into sections, so the trend today is to +leave the /usr/man tree in the state supplied by the vendor, and to +maintain a separate tree, /usr/man/man[1-8nl], to hold local +additions. Most UNIX man implementations support a MANPATH variable +to specify a search path, such as /usr/man:/usr/local/man. + +If your man command doesn't support a MANPATH variable, get the +freely-available man implementation man-1.0.tar.Z available on several +Internet archive sites, including gatekeeper.dec.com in +/.8/GNU/man-1.0.tar.Z. Some bugs exist in that version, and fixes were +supplied to the program's author on 12 December 1992, so look for a new +version, or ask Nelson Beebe <beebe@math.utah.edu> for a set of patches. +This new man implementation has some nice features, including support +for compressed files, and checking of formatted and raw file time stamps +to decide whether to reformat or not. Furthermore, it can be configured +to use either [nt]roff, or GNU groff; some UNIX vendors charge extra for +[nt]roff, so groff may offer a cheaper man page implementation. + +The last argument to .TH is the date in the form 01 December 1992; the +month is NOT abbreviated. + + +------------------------------------------------------------------------ + +*** Following +.SH NAME +should be a single line with NO macros, such as + +bibtex \- make a bibliography for (La)TeX + +This line is very important, because it is used by the "man -k" and +"apropos" commands to look up commands by keywords; every word in the +line is a potential keyword match. + + +------------------------------------------------------------------------ + +*** Following +.SH SYNOPSIS +there should be one or more lines in the form + +.B vftovp +[ +.B \-verbose +] +[ +.BI \-charcode-format =format +] +.I vf_file_name +.I tfm_file_name +[ +.I vpl_file_name +] + +Program names and option switches are typeset in bold type (.B), and +file names in italics (.I). Switch values are in italics. + +Give option switches in alphabetical order in the SYNOPSIS +section, and their descriptions in the same order in the OPTIONS +section. + + +------------------------------------------------------------------------ + +*** Here are some general [nt]roff hints for writing the +.SH DESCRIPTION +section. + + +*** Separate paragraphs by a .PP command, not by blank lines. + + +*** When using the multi-font selectors, like .BI (bold, then italic), +remember that fonts alternate in the following space-separated words: + +.BI aaa bbb ccc ddd + +will typeset aaa and cccc in bold, and bbb and ddd in italic, with NO +intervening spaces, so the result here will be aaabbbcccddd. If you +want spaces between the words, use quotation marks: + +.BI "aaa " "bbb " "ccc " ddd + +will produce aaa bbb ccc ddd. + +Use [nt]roff dotted font change sequences (.I, .B, .BI, .BR, ...) +instead of the \fX...\fP alternatives. The single exception is when +you need quotation marks in italics, such as \fIsetenv FOOBAR "foo +bar"\fP. + + +*** Represent en dashes by the current font minus (\-), and use the +same character in front of option switches. Hyphens in words, as +``multi-font'', are written with the ASCII minus sign. + + +*** Quotation marks are [nt]roff grouping commands, analogous to curly +braces in TeX files. They will NOT survive in the formatted output. +If you want typeset quotation marks, use ``phrase'', just as in TeX. + + +*** Ellipses (...) in [nt]roff are coded as .\|.\|., for the same +reason that \ldots{} is used in TeX instead of .... + + +*** UNIX is a trademark of AT&T Bell Laboratories and must be spelled +in uppercase letters. + + +*** Watch out for spaces. Unlike TeX, [nt]roff preserve ALL input +spaces. This means you cannot indent [nt]roff input for readability. +Two spaces should follow a sentence-ending period, and otherwise, only +one space should be used. Tabs are special in [nt]roff; they are used +to separate columns of tables, like & in TeX, and no other character +can be used for that purpose. The man page files in this directory +contain no tabs, and trailing blanks have been stripped from all +files. + + +*** Do not used fixed indentation dimensions for displayed material. +Instead, use .RS and .RE to mark the indented paragraphs, with .IP to +separate paragraphs: + +.RS +Blah blah blah blah blah blah blah blah blah. +Blah blah blah blah blah blah blah blah blah. +.IP +Blah blah blah blah blah blah blah blah blah. +Blah blah blah blah blah blah blah blah blah. +.RE + + +*** Use macros for phrases that require special typesetting, such as +the TeX logo, and provide both nroff and troff definitions: + +.if n .ds AB nroff-definition +.if t .ds AB troff-definition + +Macro names are exactly 2 characters long, and are referenced by \*( +prefixed to their names, e.g. \*(AB. + +If a macro expansion requires another macro, it must be given after +that macro. For example, the BibTeX and LaTeX macros follow the TeX +macro so they can use \*(TX in their definitions. + +Suitable macros have been provided for TeX, BibTeX, LaTeX, Metafont, +and Web, and adjusted for troff's default Times Roman typeface to +match their appearance with Computer Modern typefaces. + + +------------------------------------------------------------------------ + +*** The +.SH ENVIRONMENT +section should list all the relevant environment variables, with a brief +description and system defaults if appropriate. + + +*** Environment variables are spelled in uppercase letters, e.g., +TEXFONTS, and NO font size changes are made around them. When font +sizes were changed in the past, many inconsistencies were present, so +the practice has been abandoned. + + +*** Do not use fixed dimensions for indented labelled paragraphs. +Instead, use the width of the longest label, plus 2n, as follows: + +.TP \w'LONGESTLABEL'u+2n +LABEL +Blah blah blah blah blah blah blah blah blah. +.TP +LONGESTLABEL +Blah blah blah blah blah blah blah blah blah. +Blah blah blah blah blah blah blah blah blah. + +If the longest label is extremely long, pick a somewhat shorter one so +as to avoid having very short paragraph lines. + + +------------------------------------------------------------------------ + +*** Spell TeX control sequences in Roman letters, doubling the +backslash, e.g. \\input, or for better visibility, use italics +with the backslash represented as \e: + +.I \einput + +Although some [nt]roff implementations support a typewriter font which +is conventional for TeX control sequences, historically only roman, +bold, italic, and special fonts were available. + + +*** These manual pages in the *.man form are filtered by sedscript to +expand @XYZ@ into something else, producing corresponding *.1 files +which are installed in the system manual page directories. This is +used to insert local paths into the manual pages, so that for example +@TEXINPUTS@ is replaced by the local default TEXINPUTS search path. +Such paths are set at installation time in the top-level Makefile. + + +*** You can use the UNIX checknr utility to do a rudimentary validation of +your manual page files, e.g. + + checknr -c.BI.BR.IR.IB.RB.RI tex.man + +The -c.BI.BR.IR.IB.RB.RI is needed because checknr doesn't know about +the -man document style, and otherwise complains about those font +change commands. The command "make check" will run checknr with each +of the *.1 files. |
