/*
** COMMAND: pikchr
**
** Usage: %fossil pikchr [options] ?INFILE? ?OUTFILE?
**
** Accepts a pikchr script as input and outputs the rendered
** script as an SVG graphic.
**
** Options:
**
**    -div      On success, adds a DIV wrapper around the
**              resulting SVG output which limits its max-width.
**
**    -th       Process the input using TH1 before passing it to pikchr.
**
**    -th-novar Disable $var and $<var> TH1 processing. Only applies
**              with the -th flag.
**              with the -th flag. Use this if the pikchr script uses
**              '$' for its own purposes.
**
**    -th-nosvg When using -th, output the post-TH1'd script
**              instead of the pikchr-rendered output.
**
**    -th-trace Trace TH1 execution (for debugging purposes)
**
** TH1 Caveats: the built-in TH1 commands make some assumptions about
** HTML escaping and output which do not apply via this
** command. e.g. some commands will output directly to stdout, rather
** than the output buffer this command requires. Improvements in that
** regard are under consideration/construction.
** TH1 Caveats:
**
** If the -th flag is used, this command must open a fossil database
** for certain functionality to work. It will run TH1 without opening
** a db if one cannot be found in the current checkout or with the -R
** REPO flag, but any TH1 commands which require a db will then fail.
**
** Many of the fossil-installed TH1 functions do not make any sense
** for pikchr scripts
