+.SH COMPATIBILITY
+To be compatible with as many tools as possible, the output format is pre-POSIX
+ustar archive using GNU extensions where necessary. This seems to be more
+widely supported by many tar programs (besides GNU tar), even more than the
+newer POSIX format and PAX extensions.
It is not possible to store socket files in a tar or pax archive. Also, in the
current implementation, all extended attribuates are lost.
