* Module name: params
*
* -------------------------------------------------------------------------- **
*
* This module performs lexical analysis and initial parsing of a
* Windows-like parameter file. It recognizes and handles four token
* types: section-name, parameter-name, parameter-value, and
* end-of-file. Comments and line continuation are handled
* internally.
*
* The entry point to the module is function pm_process(). This
* function opens the source file, calls the Parse() function to parse
* the input, and then closes the file when either the EOF is reached
* or a fatal error is encountered.
*
* A sample parameter file might look like this:
*
* [section one]
* parameter one = value string
* parameter two = another value
* [section two]
* new parameter = some value or t'other
*
* The parameter file is divided into sections by section headers:
* section names enclosed in square brackets (eg. [section one]).
* Each section contains parameter lines, each of which consist of a
* parameter name and value delimited by an equal sign. Roughly, the
* syntax is:
*
* <file> :== { <section> } EOF
*
* <section> :== <section header> { <parameter line> }
*
* <section header> :== '[' NAME ']'
*
* <parameter line> :== NAME '=' VALUE '\n'
*
* Blank lines and comment lines are ignored. Comment lines are lines
* beginning with either a semicolon (';') or a pound sign ('#').
*
* All whitespace in section names and parameter names is compressed
* to single spaces. Leading and trailing whitespace is stripped from
* both names and values.
*
* Only the first equals sign in a parameter line is significant.
* Parameter values may contain equals signs, square brackets and
* semicolons. Internal whitespace is retained in parameter values,
* with the exception of the '\r' character, which is stripped for
* historic reasons. Parameter names may not start with a left square
* bracket, an equal sign, a pound sign, or a semicolon, because these
* are used to identify other tokens.
