This commit brings GEMPAK into the 1990's by calling on the GNU Readline library to handle the GEMPAK prompt. This allows for the arrow keys to work as you would expect, as well as other keyboard shortcuts. We assume the Readline library exists in a standard directory. Only Linux is supported with the edits here.

@sgdecker denoted to me that this change sometimes segfaults, so will need some more dev love prior to considering merging. |
