 - use a pcap filter to select IP packets (integrate patch from Brieuc and do a non regression test)
 - if no packets are received, ipfm does not dump its files.
-- lex and yacc checks do not work as expected (if no yacc or bison is present, does not stop ./configure)
+- ./configure lex and yacc checks do not work as expected (if no yacc or bison is present, does not stop ./configure)
+- add an ipfm.conf option to read packets from a file (to test IPFM without beeing root).
+- document ./configure options in INSTALL
 
 - have a better detection of long command line options (actually, #ifdef LINUX...)
