+ * 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 stipped 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.
