# Most of Hirb's functionality currently resides in Hirb::View.
# For an in-depth tutorial on creating and configuring views see Hirb::Formatter.
# Hirb has an optional yaml config file defined by config_file(). This config file
# has the following top level keys:
# [:output] This hash is used by the formatter object. See Hirb::Formatter.config for its format.
# [:width]  Width of the terminal/console. Defaults to DEFAULT_WIDTH or possibly autodetected when Hirb is enabled.
# [:height]  Height of the terminal/console. Defaults to DEFAULT_HEIGHT or possibly autodetected when Hirb is enabled.
# [:formatter] Boolean which determines if the formatter is enabled. Defaults to true.
# [:pager] Boolean which determines if the pager is enabled. Defaults to true.
# [:pager_command] Command to be used for paging. Command can have options after it i.e. 'less -r'.
#                  Defaults to common pagers i.e. less and more if detected.
