> The bootstrap script currently generates a THANKS file by grepping through the git shortlog
and running an extended regular expression command on the resulting stream using sed (line
48):
> git shortlog -se 6c976bd..HEAD \
>         | grep -v @apache.org \
>         | sed -E "s/^[[:blank:]]{5}[[:digit:]]+[[:blank:]]/ * /" >> THANKS
> BSD sed uses the '-E' option to interpret regular expressions as extended (modern) regular
expressions rather than basic regular expressions (BRE's). GNU sed uses the '-r' option for
this behavior.
> The bootstrap script should be modified to detect the proper flag to use. I am currently
using a patch which checks the system's uname to determine the flag.
