NAME

       calibre-debug - calibre-debug

          calibre-debug [options]

       Various  command  line  interfaces  useful  for  debugging  calibre. With no options, this
       command starts an embedded Python interpreter. You can also run the main calibre GUI,  the
       calibre viewer and the calibre editor in debug mode.

       It  also contains interfaces to various bits of calibre that do not have dedicated command
       line tools, such as font subsetting, the e-book diff tool and so on.

       You can also use calibre-debug to run standalone scripts. To do that use it like this:
          calibre-debug myscript.py -- --option1 --option2 file1 file2 ...

       Everything after the -- is passed to the script.

       Whenever you pass arguments to  calibre-debug  that  have  spaces  in  them,  enclose  the
       arguments in quotation marks. For example: "/some path/with spaces"

[OPTIONS]

       --add-simple-plugin

       --gui-debug

       --run-plugin, -r
              Run  a plugin that provides a command line interface. For example: calibre-debug -r

       --shutdown-running-calibre, -s
              Cause  a  running  calibre instance, if any, to be shutdown. Note that if there are
