+# Compile with the host compiler and link a .c file into a "lookup" binary, then
+# compile and optionally link together a bunch of .s or .c files with CTF info
+# and pass the name of the resulting binary to the "lookup" binary and check the
+# output.  (If none is specified, the binary is expected to generate its own CTF
+# for testing purposes.)
+#
+# As with run_dump_test, this is all driven by a file (in this case, a .lk file)
+# beginning with zero or more option lines, which specify the names of the
+# lookup binary's source file, the source file(s) with CTF info to compile
+# together, and whether to link them.  The optional lines have the syntax:
+#
+#	# OPTION: VALUE
+#
+# OPTION is the name of some option, like "name" or "lookup", and
+# VALUE is OPTION's value.  The valid options are described below.
+# Whitespace is ignored everywhere, except within VALUE.  The option
+# list ends with the first line that doesn't match the above syntax.
+# However, a line within the options that begins with a #, but doesn't
+# have a recognizable option name followed by a colon, is considered a
+# comment and entirely ignored.
+#
+# The interesting options are:
+#
+#   name: TEST-NAME
+#	The name of this test, passed to DejaGNU's `pass' and `fail'
+#	commands.  If omitted, this defaults to FILE, the root of the
+#	lookup .c file's name.
+#
+#   lookup: SOURCE
+#	Compile the file SOURCE.c.  If omitted, the lookup source defaults
+#	to FILE.c.
+#
+#   source: SOURCE
+#	Assemble the file SOURCE.c and pass it to the LOOKUP program.
+#
+#   link:
+#	If set, link the SOURCE together even if only one file is specified.
+#
+#   link_flags:
+#	If set, extra flags to pass to the linker.
+#
+#   xfail: GLOB|PROC ...
+#	This test is expected to fail on a specified list of targets.
+#
+# Each option may occur at most once unless otherwise mentioned.
+#
+# After the option lines come regexp lines.  run_lookup_test calls
+# regexp_diff to compare the output of the lookup program against the
+# regexps in FILE.d.
