# NAME
#      import - load libraries, plugins, themes, etc.
#
# SYNOPSIS
#      import <path/library>[<path/library>..]
#
# DESCRIPTION
#      Import libraries, plugins, themes, completions. Prepend existing
#      user custom/<library> directories to the path to allow users to
#      override specific functions in themes/plugins.
#
# NOTES
#      $fish_path and $fish_custom point to oh-my-fish home and the user
#      dotfiles folder respectively. Both globals are usually configured
#      in ~/.config/fish/config.fish. Also, import is clever enough to
#      skip directories with *.spec.fish files.
#
# EXAMPLES
#      import plugins/<plugin>
#      import plugins/{dpaste,cask} themes/bobthefish
