# ffmpeg[encode] is for h263 and mpeg4
# ssl, xml, vxml, ipv6, ldap, sound, wav, and video are use flags
#   herited from ptlib: feature is enabled if ptlib has enabled it
#   however, disabling it if ptlib has it looks hard (coz of buildopts.h)
#   forcing ptlib to disable it for opal is not a solution too
#   atm, accepting the "auto-feature" looks like a good solution
#   (asn is used for fax and config _only_ for examples)
# OPALDIR should not be used anymore but if a package still need it, create it
