# BB Class inspired by ebuild.sh
#
# This class will test files after installation for certain
# security issues and other kind of issues.
#
# Checks we do:
#  -Check the ownership and permissions
#  -Check the RUNTIME path for the $TMPDIR
#  -Check if .la files wrongly point to workdir
#  -Check if .pc files wrongly point to workdir
#  -Check if packages contains .debug directories or .so files
#   where they should be in -dev or -dbg
#  -Check if config.log contains traces to broken autoconf tests
#  -Check invalid characters (non-utf8) on some package metadata
#  -Ensure that binaries in base_[bindir|sbindir|libdir] do not link
#   into exec_prefix
#  -Check that scripts in base_[bindir|sbindir|libdir] do not reference
#   files under exec_prefix
