DESCRIPTION

This manual page briefly documents Therion and provides an overview of the package.

Therion is a program that processes Therion data files to produce cave surveys. The data
files are usually .th files which contain survey data (largely equivalent to Survex .svx
files), .th2 files which contain drawing data, and thconfig files which control the data
files to be used and the maps to be output.

Therion outputs PDF and SVG files for drawings, Survex .3d files, Compass .PLT files and
VRML files for 3D models.

Therion uses a number of helper programs to do its job. Survex is used to process the
centreline data, MetaPost is used to draw cave symbols, and pdfTeX generates the final
maps.

In order to make the entering of drawing data practical, and to make the editing of survey
files easier, a graphical editor XTherion is included. This also includes a 'compiler'
function which runs Therion on the data to produce output. This is implemented using
Tcl/Tk.

The Therion data files describe the cave as text in terms of objects so the corresponding
graphical representations are only inserted at output generation time. This means that a
survey can be produced using whichever symbol set you require by specifying the relevant
set of MetaPost macros. Currently the UIS symbol set is supported.

Multiple languages and character sets are supported — currently ISO-8859-1, ISO-8859-2,
ISO-8859-5, ISO-8859-7, UTF-8, ASCII and CP1250.

ARGUMENTS

       therion takes only one argument — a config-file. If no file is specified then the  default
       thconfig  file  in  the  current directory will be used. A new default file can be created
       using the -g option.

OPTIONS

This program follows the usual GNU command line syntax, with long options starting with
two dashes ("--"). A summary of options is included below. For a complete description,
see The Therion Book.

-h, --help
Show summary of options.

-v, --version
Show version information.

-q Quiet mode — minimise output.

-g Generate a new configuration file. This will be the given config-file if
specified, or thconfig in the current directory if not. If the file already
exists, it will be overwritten.

-i Ignore comments when writing (-g|-u) configuration file.

-L Do not create a log-file. Normally all messages are written into a therion.log
file.

-l log-file
Change the name of the log file.

-p search-path
This option is used to set the search path (or list of paths, separated by
colon), which therion will use to find its source files (if it doesn't find them
in the working directory).

-q Run therion in quiet mode. It will print only warning and error messages (to
STDERR).

--print-encodings
Print a list of all supported encodings.

--print-init-file
Print a default initialisation file. For more details see the Initialisation
section in the Appendix of the Therion Book.

-s Set the name of the source file.

-u Upgrade the configuration file.

-d Turn on debugging mode. The current implementation creates a temporary directory
named thTMPDIR (in your system temporary directory) and does not delete any
temporary files.
