;;; mainline.el --- modeline replacement forked from powerline.el
;; Author: Jason Milkins
;; Version: 1.0.2
;; Keywords: statusline / modeline
;;; Changelog:
;; 1.0.1 : added additional xpm shape chamfer14, adjusted chamfer xpm.
;; : mainline-color1, mainline-color2, mainline-arrow-shape
;; : - are now custom variables, to make them available via customize.
;; : - they could be set from deftheme: custom-theme-set-variables
;; : - already, so Emacs24 color themes can set them.
;;
;; 1.0 : added additional xpm shapes.
;;
;;; Commentary:
;;;
;;; This is a fork of powerline.el which I began while the original
;;; authorship of powerline was unknown, I will gladly add in
;;; accreditation to the proper author(s), please drop me a line at
;;; jasonm23@gmail.com and let me know if you have historical
;;; information about poweline.
;;;
;;; This fork will not be developed further, the powerline
;;; authors/maintainers are invited to extract the additional
;;; functionality / graphics from here, permission is preemptively
;;; given (and none is needed)
;;;
;;;
;;; Additional shapes added:
;;; chamfer, rounded, slant, slant-left, slant-right
;;;
;;; Using mainline.el.
;;;
;;; Add a require to .emacs (or install from elpa/marmalade which will
;;; setup autoloads)
;;;
;;; (require 'mainline)
;;;
;;; You can customize the separator graphic by setting the custom variable
;;;
;;; mainline-arrow-shape
;;;
;;; possible values:
;;;
;;; chamfer
;;; chamfer14 (default)
;;; rounded
;;; arrow
;;; arrow-14
;;; slant
;;; slant-left
;;; slant-right;
;;; half
;;; percent
;;; curve
;;;
