feat: support (skip) commented lines in version-file Sometimes it is convenient to be able to temporarily disable something in a version-file. Because these files often aren't necessarily tracked in a SCM, especially when working with virtualenvs, the SCM diffs won't help with showing removed lines which are currently the only way to disable something. 2021-04-05 07:22:08 +00:00			`words=($(cut -b 1-1024 "$VERSION_FILE" \| sed -n 's/^[[:space:]]\([^[:space:]#][^[:space:]]\).*/\1/p'))`
