Produces html markup from a jemdoc SOURCEFILE.
Most of the time you can use jemdoc without any additional flags.
For example, typing
jemdoc index
will produce an index.html from index.jemdoc, using a default
configuration.
Some configuration options can be overridden by specifying a
configuration file. You can use
jemdoc --show-config
to print a sample configuration file (which includes all of the
default options). Any or all of the configuration [blocks] can be
overwritten by including them in a configuration file, and running,
for example,
jemdoc -c mywebsite.conf index.jemdoc
You can view version and installation details with
jemdoc --version
See http://jemdoc.jaboc.net/ for many more details."""
