3	# SYNOPSIS
4	#
5	# YAT_CHECK_YAT([MINIMUM-VERSION], [ACTION-IF-FOUND], [ACTION-IF-NOT-FOUND])
6	#
7	# DESCRIPTION
8	#
9	# Test yat library of a particular version
10	#
11	# This macro file can be used by applications to find and use the
12	# yat library.
13	#
14	# Note: macros in this file assume that yat-config has been
15	# installed. yat-config was introduced in yat 0.5 and
16	# consequently these macros do not work with yat 0.4.x (or
17	# older).
18	#
19	# This macro calls:
20	#
21	# AC_SUBST(YAT_CPPFLAGS)
22	# AC_SUBST(YAT_CXXFLAGS)
23	# AC_SUBST(YAT_LDFLAGS)
24	# AC_SUBST(YAT_LIBS)
25	# AC_SUBST(YAT_LA_FILE)
26	# AC_SUBST(YAT_LT_ADD)
27	#
28	# defines:
29	#
30	# HAVE_YAT
31	#
32	# and sets the following variable:
33	#
34	# yat_config: If yat-config exists, $yat_config refers to it,
35	# otherwise $yat_config is set to "no".
36	#
37	#
38	# YAT_CHECK_YAT is split into sub-macros:
39	#
40	# YAT_FIND_YAT()
41	# YAT_CHECK_VERSION([MINIMUM-VERSION])
42	# YAT_CHECK_HEADER()
43	# YAT_CHECK_LIB()
44	#
45	# so when preferable, you can call any of these instead.
46	#
47	#
48	# YAT_FIND_YAT([ACTION-IF-FOUND], [ACTION-IF-NOT-FOUND])
49	#
50	# Finds the yat-config scripts. If there is no --with-yat
51	# specified, it will look in the PATH. Sets a shell variable
52	# $yat_config. $yat_config is required for the other macros and
53	# therefore if YAT_FIND_YAT has not been called, they will call
54	# YAT_FIND_YAT. If --without-yat (or equivalently --with-yat=no)
55	# is given, all tests and actions are turned off.
56	#
57	#
58	# YAT_CHECK_VERSION([MINIMUM-VERSION],[ACTION-IF-FOUND],[ACTION-IF-NOT-FOUND])
59	#
60	# If the version of yat is at least MINIMUM-VERSION, execute
61	# ACTION-IF-FOUND, otherwise execute ACTION-IF-NOT-FOUND.
62	#
63	#
64	# YAT_CHECK_HEADER([ACTION-IF-FOUND], [ACTION-IF-NOT-FOUND])
65	#
66	# If yat headers are found and compilable, call
67	# AC_SUBST(YAT_CPPFLAGS) and AC_SUBST(YAT_CXXFLAGS), define
68	# HAVE_YAT, execute ACTION-IF-FOUND. If test compilation failed
69	# execute ACTION-IF-NOT-FOUND.
70	#
71	#
72	# YAT_CHECK_LIB([ACTION-IF-FOUND], [ACTION-IF-NOT-FOUND])
73	#
74	# Compile a small program and link it to yat. On success call
75	# AC_SUBST(YAT_LDFLAGS), AC_SUBST(YAT_LIBS), AC_SUBST(YAT_LT_ADD),
76	# and AC_SUBST(YAT_LA_FILE), and define HAVE_YAT, and execute
77	# ACTION-IF-FOUND. On failure execute ACTION-IF-NOT-FOUND.
