+pdflatex.sh
+===========
+
+NAME
+----
+`pdflatex.sh` -- compile (La)TeX files and more.
+
+SYNOPSIS
+--------
+    pdflatex.sh  -h | -V
+    pdflatex.sh  [ +3 +b +i +o +p ]  FILE(.tex)
+    pdflatex.sh  -2x1 | -2x2  FILE(.pdf)
+    pdflatex.sh  -gs | -rs | -gd | -rd  DIR
+    pdflatex.sh  -b | -c | -i | -k | -kk | -l [WIDTH] | -n | -s | -ss
+                 | -sc [LANG]  FILE(.tex)
+
+DESCRIPTION
+-----------
+Bash script to compile (La)TeX files (with BibTeX, indices and PSTricks if
+necessary), convert images to include them in (La)TeX files and to manipulate
+output PDF documents.  The script also lets you check syntactic and semantic
+correctness of (La)TeX source files, e.g. with the use of *ChkTeX*.
+
+It is possible to customize programs (like PDF viewer) and its settings that
+are used by the script in **Programs** and **Options** sections in the source
+code.
+
+NOTE:  If the script is run as `pdflatex.sh` then `pdflatex` command is used
+(producing PDF output file), otherwise `latex` command is used (producing DVI
+output file).  Thus if necessary, the `latex.sh` symbolic link can be created
+to use the script easily.
+
+OPTIONS
+-------
+    -2x1 FILE            put two pages of the PDF FILE on a single A4 sheet
+                         (the output will be in FILE-nup.pdf file)
+    -2x2 FILE            put four pages of the PDF FILE on a single A4 sheet
+                         (the output will be in FILE-nup.pdf file)
+    +3                   run latex/pdflatex thrice (default is twice)
+    +b                   make also bibtex
+    -b   FILE            make ONLY bibtex
+    -c   FILE            cleanup (remove auxiliary files)
+    -gs  DIR             convert SVG images in directory DIR
+    -rs  DIR             convert SVG images in directory DIR recursively
+    -gd  DIR             convert DIA images in directory DIR
+    -rd  DIR             convert DIA images in directory DIR recursively
+    -h                   print (this) help message and exit
+    +i                   make also index
+    -i   FILE            make ONLY index
+    -k   FILE            run 'chktex' command (if available)
+    -kk  FILE            the same as '-k' but only errors are shown
+    -l   [WIDTH] FILE    check maximum line width (by default WIDTH=80)
+    -n   FILE            check non-breaking spaces
+    -s   FILE            check sentence separators
+    -ss  FILE            STRICTLY check sentence separators
+    -sc  [LANG] FILE     run interactive spell checker (by default LANG="en_GB"
+                         and UTF-8 encoding is used)
+    +o                   open PDF (or DVI) file after compilation
+    +p                   use 'ps4pdf' instead of 'pdflatex'/'latex' (PSTricks)
+    -V                   print script version
+
+EXAMPLES
+--------
+    pdflatex.sh file.tex
+
+> Compile `file.tex` source file.
+
+    pdflatex.sh +b +i +o file.tex
+
+> Compile `file.tex` with BibTeX and MakeIndex, and open PDF browser with the
+> output file after compilation.
+
+    pdflatex.sh +p file.tex
+
+> Compile `file.tex` with the use of PSTricks.
+
+    pdflatex.sh -kk file.tex
+
+> Run `chktex` command but show only errors.
+
+    pdflatex.sh -gs img/
+
+> Convert all SVG images in the directory `img/` (PDF and PS version will be
+> produced).
+
+    pdflatex.sh -2x1 file.pdf
+
+> Put two pages of the `file.pdf` on a single A4 sheet (the output should be in
+> `FILE-nup.pdf` file).
