# Most of Hirb's functionality is in Hirb::View.
# For a tutorial  on configuring and creating views see Hirb::View. For a tutorial on dynamic views see Hirb::DynamicView.
#
# == Config Files
# Hirb can have multiple config files defined by config_files(). These config files
# have 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 Hirb::View::DEFAULT_WIDTH or possibly autodetected when Hirb is enabled.
# [*:height*]  Height of the terminal/console. Defaults to Hirb::View::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.
# [*:ignore_errors*] Boolean which ignores internal view errors and continues with original view
#                    (i.e. #inspect for irb). Defaults to false.
