/* Config file format:
*
* Comments are any lines whose first non-whitespace character is ';' or '#'.
* Note that comments can also follow a value, on the same line.
* To intentionally have a '#' character in the value, use ##
*
* All parameters fall into sections. To name a section, the first
* non-whitespace character on the line will be '[', and the last will be ']'.
*
* Parameters are simple key=value pairs. Whitespace around the '=', and at the
* beginning or end of the line is ignored. Key names may not contain '=' nor
* begin with '[', however values can. If the last character of the value is
* '\', the next line (sans leading/trailing whitespace) is considered part of
* the value as well. Programmatically, the key "K" in section "S" is referred
* to as "S::K", much like C++ namespaces. For example:
* [Section1]
* # this is a comment
* foo = bar \
* baz\
* quux \
* ## this is not a comment! # this IS a comment
* means the value of "Section1::foo" is "bar bazquux # this is not a comment!"
*
* Parameters may be of several types:
* String - Bare characters. If the first and last characters are both '"',
* they are removed (so just double them if you really want quotes
* there)
* Int - A decimal number from -2147483648 to 2147483647
* UInt - A number in decimal, hex, or octal from 0 to 4294967295 (or
* 0xffffffff, or 037777777777)
* Bool - true/false, 0/1, on/off, yes/no
*
* Of course, the actual accepted values for a parameter may be further
* restricted ;)
