Very cool. However...
$ uname -spr
FreeBSD 8.1-RELEASE-p1 amd64
$ which augtool
$ type augtool
-bash: type: augtool: not found
Not like I'm running bare...
$ pkg_info -Ia | wc -l
399
Unfortunately, augtool doesn't even appear to be packaged for FreeBSD:
$ pwd
/repos/FreeBSD-8.1/8.1-RELEASE/packages
$ ls | head -4
All
INDEX
MOVED
UPDATING
$ awk -F'|' '/augtool/ {print $1}' < INDEX
$ awk -F'|' '/lexx/ {print $1}' < INDEX
lexxia-0.901
$ awk -F'|' '/yacc/ {print $1}' < INDEX
afay-041111
byaccj-1.14
ebnf2yacc-0.1.1
lemon-1.69
ruby18-byaccr-0.1
showgrammar-1.1
cocor-1.7_1
Not as a binary package nor could I find it in the ports tree.
At this point, we're developing a script that is to be a candidate for
inclusion into the base-distribution of FreeBSD, so any/all use of
augtool is out unless it gets included in the base OS.
Thanks for the heads-up though... looks really powerful.
