#
# SYNOPSIS
#
#   MS_PROG_PGCLIENT()
#
# DESCRIPTION
#
#   This macro searches for a program called 'pgclient'. If found the
#   variable $pgclient is set to its path. Else it is set to 0. An
#   option is added to the configure script for setting an search path
#   instead of $PATH ($pgclient_dir). If pgclient is necessary for
#   installing your program, you can do something like the following to
#   stop configure with an error if pgclient wasn't found:
#
#         if test "x$pgclient" = "x0"; then AC_MSG_ERROR([We need that to setup the database!]); fi
#
#   pgclient can be found at http://pgclient.freesources.org
