# SYNOPSIS
#
# AX_LIB_MYSQL([MINIMUM-VERSION])
#
# DESCRIPTION
#
# This macro provides tests of availability of MySQL client library of
# particular version or newer.
#
# AX_LIB_MYSQL macro takes only one argument which is optional. If there
# is no required version passed, then macro does not run version test.
#
# The --with-mysql option takes one of three possible values:
#
# no - do not check for MySQL client library
#
# yes - do check for MySQL library in standard locations (mysql_config
# should be in the PATH)
#
# path - complete path to mysql_config utility, use this option if
# mysql_config can't be found in the PATH
#
# This macro calls:
#
# AC_SUBST(MYSQL_CFLAGS)
# AC_SUBST(MYSQL_LDFLAGS)
# AC_SUBST(MYSQL_VERSION)
#
# And sets:
#
# HAVE_MYSQL

# SYNOPSIS
#
# AX_LIB_SQLITE3([MINIMUM-VERSION])
#
# DESCRIPTION
#
# Test for the SQLite 3 library of a particular version (or newer)
#
# This macro takes only one optional argument, required version of SQLite
# 3 library. If required version is not passed, 3.0.0 is used in the test
# of existance of SQLite 3.
#
# If no intallation prefix to the installed SQLite library is given the
# macro searches under /usr, /usr/local, and /opt.
#
# This macro calls:
#
# AC_SUBST(SQLITE3_CFLAGS)
# AC_SUBST(SQLITE3_LDFLAGS)
# AC_SUBST(SQLITE3_VERSION)
#
# And sets:

# SYNOPSIS
#
# AX_CHECK_OPENSSL([action-if-found[, action-if-not-found]])
#
# DESCRIPTION
#
# Look for OpenSSL in a number of default spots, or in a user-selected
# spot (via --with-openssl). Sets
#
# OPENSSL_INCLUDES to the include directives required
# OPENSSL_LIBS to the -l directives required
# OPENSSL_LDFLAGS to the -L or -R flags required
#
# and calls ACTION-IF-FOUND or ACTION-IF-NOT-FOUND appropriately
#
# This macro sets OPENSSL_INCLUDES such that source files should use the
# openssl/ directory in include directives:
#
# #include <openssl/hmac.h>

#
# DESCRIPTION
#
# check for pcre lib and set PCRE_LIBS and PCRE_CFLAGS accordingly.
#
# also provide --with-pcre option that may point to the $prefix of the
# pcre installation - the macro will check $pcre/include and $pcre/lib to
# contain the necessary files.
#
# the usual two ACTION-IF-FOUND / ACTION-IF-NOT-FOUND are supported and
# they can take advantage of the LIBS/CFLAGS additions.

# DESCRIPTION
#
# This macro figures out what libraries are required on this platform to

#
# The common cases are not to need any extra libraries, or to need
# -lsocket and -lnsl. We need to avoid linking with libnsl unless we need
# it, though, since on some OSes where it isn't necessary it will totally
# break networking. Unisys also includes gethostbyname() in libsocket but
# needs libnsl for socket().
