annotate trunk/src/dil/Token.d @ 391:33b566df6af4

Migrated project to Tango. Decremented the numbers of the format placeholders in the localized messages by one. Replaced all instances of writef/ln with Stdout. Added module common.d with string aliases and a global Layout!(char) instance. Replaced %s format specifiers with index placeholders in html/xml_tags. Changed member Information.arguments to string message. Copied std.metastring, std.uni and std.utf from Phobos.
