Create a python script for signing a file

[dashohoxha]

Create a python script called gpg-sign.py which takes as arguments the key and the file to be signed and signs it using GPGME functions, in a similar way to this command:

• https://github.com/EasyGnuPG/egpg/blob/gnupg-2.1/src/cmd/sign.sh#L18

Then replace the command above with a call to the script gpg-sign.py.

Please remove the directory pgpg (rm -rf pgpg/) and clone it again (git clone https://github.com/EasyGnuPG/pgpg) because I have changed the branches and this may confuse git.
