# Description
#   Run a git command for all available repositories, starting from $CODE_ROOT_DIR.
#   NB: it ignores all directories whose name starts with a '_' and everything below them unless you supply '.' as the
#   first argument (see below).
# Arguments
#   $1 - if '.' is passed as first argument, search starts from the current dir instead of $CODE_ROOT_DIR and
#        directories starting with '_' are not ignored
#   $@ - Any arguments to be passed to git
#=======================================================================================================================
