tklib diagram files

diagram-viewer is based upon the package diagram. See it for examples and language
reference.

USE CASES
diagram-viewer was written with the following two use cases in mind.

[1] Processing and display of one or more diagram files.

[2] Batch conversion of one or more diagram files into raster image files.

COMMAND LINE
diagram-viewer show inputfile...
This is the form for use case [1]. The application opens a gui showing the list of
input files to the left, allowing the user to choose which of them to render to the
canvas on the right.

diagram-viewer convert -o output format inputfile...
This is the form for use case [2]. The application converts the input files into
raster image of the specified format.

path output (in)
This argument specifies where to write the generated image. It can be the
path to a file or directory.

If the output does not exist then [file dirname $output] has to exist and
must be a writable directory.

In case of multiple input files the generated image will be written to a
file in the directory, and the name of that file will be derived from the
inputfile, and format.

In case of a single input file the generated image will be written to the
file.

(handle) format (in)
This argument specifies the image format to convert the diagrams into when
processing the input. The application recognizes all formats supported by
the Img package, i.e. for which it can load a package img::format

path inputfile (in)
This argument specifies the path to the diagram file to process. It has to
exist, must be readable, and written in diagram format.
