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. + +Using the \`tidy' mode brings several advantages: + - the current directory is not cluttered with plethora of temporary files. + - clutter can be even further reduced using --build-dir=dir: all the *.t2d + directories are stored there. + - clutter can be reduced to zero using, e.g., --build-dir=/tmp/\$USER.t2d + or --build-dir=\$HOME/.t2d. + - the output file is updated after every successful TeX run, for + sake of concurrent visualization of the output. In a \`local' build + the viewer stops during the whole TeX run. + - if the compilation fails, the previous state of the output file + is preserved. + - PDF and DVI compilation are kept in separate subdirectories + preventing any possibility of auxiliary file incompatibility. + +On the other hand, because \`tidy' compilation takes place in another +directory, occasionally TeX won't be able to find some files (e.g., when +using \\graphicspath): in that case, use -I to specify the additional +directories to consider. + +The values of the BIBER, BIBTEX, DVIPDF, DVIPS, HEVEA, LATEX, MAKEINDEX, +MAKEINFO, PDFLATEX, PDFTEX, SED, T4HT, TEX, TEX4HT, TEXINDEX, and THUMBPDF_CMD +environment variables are used to run those commands, if they are set. + +Regarding --dvipdf, if DVIPDF is not set in the environment, the +following programs are looked for (in this order): dvipdfmx dvipdfm +dvipdf dvi2pdf dvitopdf. + +Any CMD strings are added after @setfilename for Texinfo input, or in +the first line for LaTeX input. + +Report bugs to bug-texinfo@gnu.org, +general questions and discussion to help-texinfo@gnu.org. +GNU Texinfo home page: <http://www.gnu.org/software/texinfo/> +General help using GNU software: <http://www.gnu.org/gethelp/> +EOF + exit 0 +} + + +# verbose WORD1 WORD2 +# ------------------- +# Report some verbose information. +verbose () +{ + if $verb; then + echo >&2 "$0: $@" + fi +} + + +# version +# ------- +# Display version info and exit successfully. +version () +{ + cat <<EOF +texi2dvi (GNU Texinfo 5.2) $rcs_version + +Copyright (C) 2014 Free Software Foundation, Inc. +License GPLv3+: GNU GPL version 3 or later <http://gnu.org/licenses/gpl.html> +This is free software: you are free to change and redistribute it. +There is NO WARRANTY, to the extent permitted by law. +EOF + exit 0 +} + + +## ---------------- ## +## Handling lists. ## +## ---------------- ## + + +# list_append LIST-NAME ELEM +# -------------------------- +# Set LIST-NAME to its former contents, with ELEM appended. +list_append () +{ + local la_l="$1" + shift + eval set X \$$la_l "$@" + shift + eval $la_l=\""$@"\" +} + + +# list_concat_dirs LIST-NAME DIR-LIST +# ----------------------------------- +# Append to LIST-NAME all the components (included empty) from +# the $path_sep separated list DIR-LIST.
