* String interpolation. Expressions like "--with-freetype2-library=" + freetype + "/lib" can now be written as "--with-freetype2-library=${freetype}/lib" An arbitrary expression can be enclosed within ${...}, not just identifiers. * Escaping in string literals: \n, \r, \t interpreted as in C, any other character following \ is interpreted as-is. * Newlines are now allowed in string literals. 2006-05-01 14:01:47 +00:00			`"foo" + "bar"`

* Allow "$" in strings as long as they are not followed by "{". (Too bad flex doesn't have lexical restrictions, the current solution isn't quite right...) 2006-09-01 12:04:06 +00:00			`+ "foo$bar"`
