/* Config file format:
|
|
*
|
|
* Comments are any lines whose first non-whitespace character is ';' or '#'.
|
|
* Note that comments must be on lines by themselves, they cannot "end" a
|
|
* normal line.
|
|
*
|
|
* 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!
|
|
* 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 ;)
