# Info Options {{{


# Info
# What to display and in what order.
# You can use ANY bash syntax in the function below!
# For example you could use if statments to only print info
# when a condition is true!
#
# The script comes with two helper functions:
# info:
#       info "subtitle" funcname
# prin:
#       prin "Custom message to print"
#       prin "Subtitle: Custom message to print"
#       prin "Subtitle: $(date)"
#
# You can also just use printf / echo to add lines but you'll
# need to prefix your msg with "${padding}", for example:
# echo -e "${padding} My custom message here"
#
# Info functions enabled by default are:
# "title" "distro" "kernel" "uptime" "packages"
# "shell" "resolution" "windowmanager" "gtktheme"
# "gtkicons" "cpu" "memory" "cols"
#
# Info functions that are disabled by default are:
# "resolution" "song" "visualstyle" "gpu"
#
# See this wiki page for more info:
