+# NOTES:
+# 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
