Subject: checkbashisms: add initial class to run against ${S}
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=fd2d95283d2b1e78fc0842ae07618a69ce5b5ac3;p=openembedded.git

checkbashisms: add initial class to run against ${S}

Currently requires that you already have checkbashisms available somewhere in
your PATH.  Runs against all '#!/bin/sh' scripts in ${S}, to attempt to find
and fix issues with /bin/sh not being bash.
