License #1
Description
Hello,
The README.md file currently states:
GPL. Based on dtach by Ned T. Crigler.
Which GPL exactly? There are many: GPL-3.0-or-later, GPL-3.0-only, GPL-2.0-or-later, GPL-2.0-only, GPL-1.0-or-later, GPL-1.0-only.
If you're not sure, I suggest sticking with the same licence used by the original dtach — GPL-2.0-only.
I also suggest adding a COPYING or LICENSE file to the root directory with the text of the chosen license for easier recognition.
Thanks for the project!
