;; Emacs PramgataPro 0.828 Ligatures Support
;; Author: lumiknit (aasr4r4@gmail.com)
;; Version: 20200211
;; Usage: Use "M-x 'pragmatapro-lig-mode' RET" to turn on ligature minor mode.
;; Or, use 'pragmatapro-lig-global-mode to turn it on globally.
;; I recommend you to compile this file before load it.
