+#   convert_bootptab	Jeroen.Scheerder@let.ruu.nl 02/25/94
+#	This script can be used to convert bootptab files in old format
+#	to new (termcap-like) bootptab files
+#
+# The old format - real entries are commented out by '###'
+#
+# Old-style bootp files consist of two sections.
+# The first section has two entries:
+# First, a line that specifies the home directory
+# (where boot file paths are relative to)
+
+###/tftpboot
+
+# The next non-empty non-comment line specifies the default bootfile
+
+###no-file
+
+# End of first section - indicated by '%%' at the start of the line
+
+###%%
+
+# The remainder of this file contains one line per client
+# interface with the information shown by the table headings
+# below. The host name is also tried as a suffix for the
+# bootfile when searching the home directory (that is,
+# bootfile.host)
+#
+# Note that htype is always 1, indicating the hardware type Ethernet.
+# Conversion therefore always yields ':ha=ether:'.
+#
+# host	htype	haddr	iaddr	bootfile
+#
+
+###somehost	1	00:0b:ad:01:de:ad	128.128.128.128	dummy
+
+# That's all for the description of the old format.
+# For the new-and-improved format, see bootptab(5).
