#
# SYNOPSIS
#
# AX_BERKELEY_DB([MINIMUM-VERSION [, ACTION-IF-FOUND [, ACTION-IF-NOT-FOUND]]])
#
# DESCRIPTION
#
# This macro tries to find Berkeley DB. It honors MINIMUM-VERSION if
# given.
#
# If libdb is found, DB_HEADER and DB_LIBS variables are set and
# ACTION-IF-FOUND shell code is executed if specified. DB_HEADER is set to
# location of db.h header in quotes (e.g. "db3/db.h") and
# AC_DEFINE_UNQUOTED is called on it, so that you can type
#
# #include DB_HEADER
#
# in your C/C++ code. DB_LIBS is set to linker flags needed to link
# against the library (e.g. -ldb3.1) and AC_SUBST is called on it.
#
# when specified user-selected spot (via --with-libdb) also sets
#
# DB_CPPFLAGS to the include directives required
# DB_LDFLAGS to the -L flags required
