# `git_premaster.sh` takes 3 parameters:                               #
#   1. Commit message (character) [mandatory]                          #
#   2. Lazy website generation (logical), with FALSE only changed      #
#      files will be processed [defaults to TRUE]                      #
#   3. Version number to be used in DESCRIPTION and NEWS.md            #
#      [defaults to current tag and last commit number + 9000]         #
#                                                                      #
