+To: bug-bash@ai.mit.edu
+Subject: X bitmap for bash
+
+ Since other GNU software comes with its very own X bitmap, I
+ thought it was about time bash had one too & here it is! To use,
+ stick the stuff after my signature in a file <path>/bash.xbm. If
+ using a twm window manager, insert the lines:
+
+IconDirectory "<path>"
+Icons {
+ "<xterm title>" "bash.xbm"
+}
+ in your ~/.twmrc file. The <xterm title> can be a prefix, so if
+ you have titles "bash@machine", the prefix "bash" will do. I'm not
+ familiar enough with other window managers, but they should be
+ similar.
+
+ If you like it, you're welcome to it...
+
+ Simon.

+# Configuration subroutine to validate and canonicalize a configuration type.

+# If it is invalid, we print an error message on stderr and exit with code 1.
+# Otherwise, we print the canonical config type on stdout and succeed.

+
+# This file is supposed to be the same for all GNU packages
+# and recognize all the CPU types, system types and aliases
+# that are meaningful with *any* GNU software.
+# Each package is responsible for reporting which valid configurations
+# it does not support. The user should be able to distinguish
+# a failure to support a valid configuration from a meaningless
+# configuration.
+
+# The goal of this file is to map all the various variations of a given
+# machine specification into a single specification in the form:
+# CPU_TYPE-MANUFACTURER-OPERATING_SYSTEM
+# or in some cases, the newer four-part form:
+# CPU_TYPE-MANUFACTURER-KERNEL-OPERATING_SYSTEM
+# It is wrong to echo any other type of specification.
+
+# The "shellcheck disable" line above the timestamp inhibits complaints
+# about features and limitations of the classic Bourne shell that were
+# superseded or lifted in POSIX. However, this script identifies a wide
+# variety of pre-POSIX systems that do not have POSIX shells at all, and
+# even some reasonably current systems (Solaris 10 as case-in-point) still
+# have a pre-POSIX /bin/sh.

+ * man2html will add links to the converted manpages. The function add_links
+ * is used for that. At the moment it will add links as follows, where
+ * indicates what should match to start with:
+ * ^^^
+ * Recognition Item Link
+ * ----------------------------------------------------------
+ * name(*) Manpage ../man?/name.*
+ * ^
+ * name@hostname Email address mailto:name@hostname
+ * ^
+ * method://string URL method://string
+ * ^^^
+ * www.host.name WWW server http://www.host.name
+ * ^^^^
+ * ftp.host.name FTP server ftp://ftp.host.name
+ * ^^^^
+ * <file.h> Include file file:/usr/include/file.h
+ * ^^^
+ *
+ * Since man2html does not check if manpages, hosts or email addresses exist,
+ * some links might not work. For manpages, some extra checks are performed
+ * to make sure not every () pair creates a link. Also out of date pages
+ * might point to incorrect places.
+ *
+ * The program will not allow users to get system specific files, such as
+ * /etc/passwd. It will check that "man" is part of the specified file and
+ * that "/../" isn't. Even if someone manages to get such file, man2html will
+ * handle it like a manpage and will usually not produce any output (or crash).
+ *
+ * If you find any bugs when normal manpages are converted, please report
+ * them to me (rcb5@win.tue.nl) after you have checked that man(1) can handle
+ * the manpage correct.
+ *
+ * Known bugs and missing features:
+ *
+ * * Equations are not converted at all.
+ * * Tables are converted but some features are not possible in html.
+ * * The tabbing environment is converted by counting characters and adding
+ * spaces. This might go wrong (outside <PRE>)
+ * * Some pages look better if man2html works in troff mode, especially pages
+ * with tables. You can decide at compile time which made you want to use.
+ *
+ * -DNROFF=0 troff mode
+ * -DNROFF=1 nroff mode (default)
+ *
+ * if you install both modes, you should compile with the correct CGIBASE.
+ * * Some manpages rely on the fact that troff/nroff is used to convert
+ * them and use features which are not descripted in the man manpages.
+ * (definitions, calculations, conditionals, requests). I can't guarantee
+ * that all these features work on all manpages. (I didn't have the
+ * time to look through all the available manpages.)

+Usage: $program [OPTION]... FILE...
+ or: texi2pdf [OPTION]... FILE...
+ or: pdftexi2dvi [OPTION]... FILE...
+
+Run each Texinfo or (La)TeX FILE through TeX in turn until all
+cross-references are resolved, building all indices. The directory
+containing each FILE is searched for included files. The suffix of FILE
+is used to determine its language ((La)TeX or Texinfo). To process
+(e)plain TeX files, set the environment variable LATEX=tex.
+
+When invoked as \`texi2pdf' or given the option --pdf generate PDF output.
+Otherwise, generate DVI.
+
+General options:
+ -D, --debug turn on shell debugging (set -x)
+ -h, --help display this help and exit successfully
+ -o, --output=OFILE leave output in OFILE; only one input FILE is allowed
+ -q, --quiet no output unless errors
+ -v, --version display version information and exit successfully
+ -V, --verbose report on what is done
+ --max-iterations=N don't process files more than N times [$max_iters]
+ --mostly-clean remove auxiliary files or directories from
+ previous runs (but not the output)
+
+Output format:
+ --dvi output a DVI file [default]
+ --dvipdf output a PDF file via DVI (using a dvi-to-pdf program)
+ --html output an HTML file from LaTeX, using HeVeA
+ --info output an Info file from LaTeX, using HeVeA
+ -p, --pdf use pdftex or pdflatex for processing
+ --ps output a PostScript file via DVI (using dvips)
+ --text output a plain text file from LaTeX, using HeVeA
+
+TeX tuning:
+ -E, --expand macro expansion using makeinfo
+ -I DIR search DIR for Texinfo files
+ -l, --language=LANG specify LANG for FILE, either latex or texinfo
+ --no-line-error do not pass --file-line-error to TeX
+ --shell-escape pass --shell-escape to TeX
+ --src-specials pass --src-specials to TeX
+ --translate-file=FILE use given charset translation file for TeX
+ -t, --command=CMD insert CMD in copy of input file
+
+Build modes:
+ --build=MODE specify the treatment of auxiliary files [$build_mode]
+ --tidy same as --build=tidy
+ -c, --clean same as --build=clean
+ --build-dir=DIR specify where the tidy compilation is performed;
+ implies --tidy;
+ defaults to TEXI2DVI_BUILD_DIRECTORY [$build_dir]
+
+The MODE specifies where the TeX compilation takes place, and, as a
+consequence, how auxiliary files are treated. The build mode can also
+be set using the environment variable TEXI2DVI_BUILD_MODE.
+
+Valid values of MODE are:
+ \`local' compile in the current directory, leaving all the auxiliary
+ files around. This is the traditional TeX use.
+ \`tidy' compile in a local *.t2d directory, where the auxiliary files
+ are left. Output files are copied back to the original file.
+ \`clean' same as \`tidy', but remove the auxiliary directory afterwards.
+ Every compilation therefore requires the full cycle.
+
+The values of these environment variables are used to run the
+corresponding commands, if they are set:
+
+ BIBER BIBTEX DVIPDF DVIPS EGREP HEVEA LATEX MAKEINDEX MAKEINFO
+ PDFLATEX PDFTEX SED T4HT TEX TEX4HT TEXINDEX TEXINDY THUMBPDF_CMD
+
+Regarding --dvipdf, if DVIPDF is not set in the environment, the
+following programs are looked for (in this order): dvipdfmx dvipdfm
+dvipdf dvi2pdf dvitopdf.
+
+If Texinfo is installed on your site, then the command
+
+ info texi2dvi
+
+should give you access to more documentation.
