devel: script to calculate a list of authors. As an initial heuristic, report anyone with at least 15 lines of code in the current source tree. Test corpora are excluded, although probabably this doesn't change much about the list of authors produced. 2020-06-03 13:05:12 -03:00			`#!/bin/sh`

Fix author-scan.sh on BSD systems. BSD xargs does not have the -d option. Here we use tr to convert newlines to NUL characters, then pass -0 to xargs (which BSD does support). I looked at passing -z to 'git ls-files', but I did not find a BSD grep option to turn on NUL deliminted line processing. 2021-02-13 10:22:43 -08:00			`git ls-files \| grep -v -e "$FILE_EXCLUDE" \| tr '\n' '\0' \| xargs -0 -n 1 \`
