-# History:
-#   2002-08-29 created by Peter Oberparleiter <Peter.Oberparleiter@de.ibm.com>
-#                         IBM Lab Boeblingen
-#   2002-09-05 / Peter Oberparleiter: implemented --kernel-directory +
-#                multiple directories
-#   2002-10-16 / Peter Oberparleiter: implemented --add-tracefile option
-#   2002-10-17 / Peter Oberparleiter: implemented --extract option
-#   2002-11-04 / Peter Oberparleiter: implemented --list option
-#   2003-03-07 / Paul Larson: Changed to make it work with the latest gcov 
-#                kernel patch.  This will break it with older gcov-kernel
-#                patches unless you change the value of $gcovmod in this script
-#   2003-04-07 / Peter Oberparleiter: fixed bug which resulted in an error
-#                when trying to combine .info files containing data without
-#                a test name
-#   2003-04-10 / Peter Oberparleiter: extended Paul's change so that LCOV
-#                works both with the new and the old gcov-kernel patch
-#   2003-04-10 / Peter Oberparleiter: added $gcov_dir constant in anticipation
-#                of a possible move of the gcov kernel directory to another
-#                file system in a future version of the gcov-kernel patch
-#   2003-04-15 / Paul Larson: make info write to STDERR, not STDOUT
-#   2003-04-15 / Paul Larson: added --remove option
-#   2003-04-30 / Peter Oberparleiter: renamed --reset to --zerocounters
-#                to remove naming ambiguity with --remove
-#   2003-04-30 / Peter Oberparleiter: adjusted help text to include --remove
-#   2003-06-27 / Peter Oberparleiter: implemented --diff
-#   2003-07-03 / Peter Oberparleiter: added line checksum support, added
-#                --no-checksum
-#   2003-12-11 / Laurent Deniel: added --follow option
-#   2004-03-29 / Peter Oberparleiter: modified --diff option to better cope with
-#                ambiguous patch file entries, modified --capture option to use
-#                modprobe before insmod (needed for 2.6)
-#   2004-03-30 / Peter Oberparleiter: added --path option
-#   2004-08-09 / Peter Oberparleiter: added configuration file support
-#   2008-08-13 / Peter Oberparleiter: added function coverage support
