Fossil

You could also use "printf()" instead of "fossil_print()" to generate
the output text, if desired.  But "fossil_print()" is recommended as
it has extra logic to insert \r characters at the right times on
windows systems.

Once you have the command running, you can then start adding code to
make it do useful things.  There are logs of utility functions in
make it do useful things.  There are lots of utility functions in
Fossil for parsing command-line options and for
opening and accessing and manipulating the repository and
the working check-out.  Study at the implementations of existing commands
to get an idea of how things are done.  You can easily find the implementations
of existing commands by searching for "COMMAND: <i>name</i>" in the
files of the "src/" directory.
