[edk2-devel] [edk2-staging/EdkRepo] [PATCH V2 2/3] EdkRepo: Add command completion setup to install.py
Nate DeSimone

Fri Apr 3 23:49:31 UTC 2020
Add configuration of command completion scripts
to install.py This enables edkrepo command completions
to work "out of box" on most Linux systems by appending
to the user's .bashrc and .zshrc startup scripts
inclusion of the EdkRepo command completion scripts.
