+# usage scancvslog.pl logfile starttime tag
+#
+# this will extract all entries from the specified cvs log file
+# that have a date later than or equal to starttime and a tag
+# value of tag. If starttime is not specified, all entries are
+# extracted. If tag is not specified then entries for all
+# branches are extracted. starttime must be specified as
+# "monthname day, year"
+#
+# Example to extract all entries for SAMBA_2_2 branch from the
+# log file named cvs.log 
+#
+# scancvslog.pl cvs.log "" SAMBA_2_2

+#
+# To extract all log entries after Jan 10, 1999 (Note month name
+# must be spelled out completely).
