One directory up (..) from where your script is (dirname $0), there is a directory called "config". In there is a file called "config". The line sources that file into your current shell environment.

Code:
. `dirname $0`/../config/config
=
source `dirname $0`/../config/config
=
. ${0%/*}/../config/config

NAME
nsd-checkconf - NSD configuration file checker. SYNOPSIS
nsd-checkconf [-v] [-h] [-o option] [-z zonename] [-s keyname] configfile DESCRIPTION
nsd-checkconf reads a configuration file. It prints parse errors to standard error, and performs additional checks on the contents. The configfile format is described in nsd.conf(5). The utility of this program is to check a config file for errors before using it in nsd(8) or zonec(8). This program can also be used for shell scripts to access the nsd config file, using the -o and -z options. OPTIONS
-v After reading print the options to standard output in configfile format. Without this option, only success or parse errors are reported. -h Print usage help information and exit. -o option Return only this option from the config file. This option can to be used in conjunction with the -z option. The special value zones prints out a list of configured zones. This option is primarily used by nsdc to parse the config file from the shell. If the -z option is given, but the -o option is not given, nothing is printed. -s keyname Prints the key secret (base64 blob) configured for this key in the config file. Used to help shell scripts parse the config file. -z zonename Return the option specified with -o for zone 'zonename'. If this option is not given, the server section of the config file is used. This option is primarily used by nsdc to parse the con- fig file from the shell. The -o, -s and -z option print configfile options to standard output. FILES
