samba-mirror/third_party/heimdal_build/wscript_configure

#!/usr/bin/env python
# Waf build script for Samba 4's bundled Heimdal.

# Unless explicitly requested by the user (e.g.
# "./configure --bundled-libraries=!asn1_compile") this will always use the
# bundled Heimdal, even if a system heimdal was found. The reason
# for this is that our checks for the system heimdal are not accurate
# enough yet to know if it is usable (some bug fix might be missing,
# compile_et might not generate the expected code, etc).
