Detailed Description

A lightweight implementation of the Defaults interface that uses simple ASCII text files.

Create instances of these objects passing in the name of a file. Each line of the file should contain a parameter setting like

name = value

Anything following a `;' or `#' is stried off; leading and trailing whitespaces on value are also removed. Blank lines are ignored.

User can also pass an argument list to the constructor. After the default ASCII input file is read, the argument list will be scanned, to possibly override some of the parameter settings. An argument of the form

–name=value

is equivalent to the parameter setting

name = value

while

–name

is equivalent to

name = 1

and

–noname

is equivalent to

name = 0.
