.SH DESCRIPTION
These are a set of functions used to implement the command-line utilities and
demonstration programs for Cdk.
Rather than set the programs' options at initialization,
they construct a simple database which holds the common parameters
using \fBCDKparseParams()\fP.
.
.SH AVAILABLE FUNCTIONS
.TP 5
.B CDKparamNumber
Retrieves an integer (or boolean) option value from the parsed command-line.
.TP 5
.B CDKparamNumber2
Retrieves an optional integer (or boolean) value from the parsed command-line.
If the command line option is not present, the \fImissing\fP value is used.
.TP 5
.B CDKparamString
Retrieves a string option value from the parsed command-line.
.TP 5
.B CDKparamString2
Retrieve an optional string option value from the parsed command-line.
.TP 5
.B CDKparamValue
Retrieve an integer (or boolean) option value from the parsed command-line.
.TP 5
.B CDKparseParams
Parse the given argc/argv command-line, with the options passed to
getopt()'s 3rd parameter.
.TP 5
.B CDKparsePosition
Parse the string as one of CDK's positioning keywords, or an actual position.
