# NAME
crio.conf - Syntax of CRIO configuration file

# DESCRIPTION
The CRIO configuration file specifies all of the available command-line options
for the crio(8) program, but in a TOML format that can be more easily modified
and versioned.

# FORMAT
The [TOML format][toml] is used as the encoding of the configuration file.
Every option and subtable listed here is nested under a global "crio" table.
No bare options are used. The format of TOML can be simplified to:

    [table]
    option = value

    [table.subtable1]
    option = value

    [table.subtable2]
    option = value
