The file consists of modules and parameters. A module begins with
the name of the module in square brackets and continues until the
next module begins. Modules contain parameters of the form
name = value.
The file is line-based -- that is, each newline-terminated line
represents either a comment, a module name or a parameter.
Only the first equals sign in a parameter is significant.
Whitespace before or after the first equals sign is discarded.
Leading, trailing and internal whitespace in module and parameter
names is irrelevant. Leading and trailing whitespace in a
parameter value is discarded. Internal whitespace within a
parameter value is retained verbatim.
Any line beginning with a hash (#) is ignored, as are lines
containing only whitespace. (If a hash occurs after anything
other than leading whitespace, it is considered a part of the
line's content.)
Any line ending in a \ is "continued" on the next line in the
customary UNIX fashion.
The values following the equals sign in parameters are all either
a string (no quotes needed) or a boolean, which may be given as
yes/no, 0/1 or true/false. Case is not significant in boolean
values, but is preserved in string values.
