// the character '\n' separates lines ..

// as comments and will be ignored.
// Any other line is considered as an attribute setting instruction and it

// attribute value which consists of the concatenation of all non-white space
// tokens before the colon. These tokens will have spaces eseparating them.
// The attribute vlue is the first token after the colon (any thing after
// it will be ignored ;
// For example :
// if the configuration file has the following entry:
//
// NO. ITERATIONS MODEL 2 : 10
//
// then the attribute is "NO. ITERATIONS MODEL 2" , and the attribute value
// is "10" (these do not include the quotation marks).
