20	#
21	# DESCRIPTION
22	#
23	# This macro provides tests of availability of MySQL client library
24	# of particular version or newer.
25	#
26	# AX_LIB_MYSQL macro takes only one argument which is optional. If
27	# there is no required version passed, then macro does not run
28	# version test.
29	#
30	# The --with-mysql option takes one of three possible values:
31	#
32	# no - do not check for MySQL client library
33	#
34	# yes - do check for MySQL library in standard locations
35	# (mysql_config should be in the PATH)
36	#
37	# path - complete path to mysql_config utility, use this option if
38	# mysql_config can't be found in the PATH
39	#
40	# This macro calls:
41	#
42	# AC_SUBST(MYSQL_CFLAGS)
43	# AC_SUBST(MYSQL_LDFLAGS)
44	# AC_SUBST(MYSQL_VERSION)
45	#
46	# And sets:

168	#
169	# DESCRIPTION
170	#
171	# This macro will check various standard spots for OpenSSL including
172	# a user-supplied directory. The user uses '--with-ssl' or
173	# '--with-ssl=/path/to/ssl' as arguments to configure.
174	#
175	# If OpenSSL is found the include directory gets added to CFLAGS and
176	# CXXFLAGS as well as '-DHAVE_SSL', '-lssl' & '-lcrypto' get added to
177	# LIBS, and the libraries location gets added to LDFLAGS. Finally
178	# 'HAVE_SSL' gets set to 'yes' for use in your Makefile.in I use it
179	# like so (valid for gmake):
180	#
181	# HAVE_SSL = @HAVE_SSL@
182	# ifeq ($(HAVE_SSL),yes)
183	# SRCS+= @srcdir@/my_file_that_needs_ssl.c
184	# endif
185	#
186	# For bsd 'bmake' use:
187	#
188	# .if ${HAVE_SSL} == "yes"
189	# SRCS+= @srcdir@/my_file_that_needs_ssl.c

603	# SYNOPSIS
604	#
605	# AX_LIB_SQLITE3([MINIMUM-VERSION])
606	#
607	# DESCRIPTION
608	#
609	# Test for the SQLite 3 library of a particular version (or newer)
610	#
611	# This macro takes only one optional argument, required version of
612	# SQLite 3 library. If required version is not passed, 3.0.0 is used
613	# in the test of existance of SQLite 3.
614	#
615	# If no intallation prefix to the installed SQLite library is given
616	# the macro searches under /usr, /usr/local, and /opt.
617	#
618	# This macro calls:
619	#
620	# AC_SUBST(SQLITE3_CFLAGS)
621	# AC_SUBST(SQLITE3_LDFLAGS)
622	# AC_SUBST(SQLITE3_VERSION)
623	#
624	# And sets:
625	#
626	# HAVE_SQLITE3
