 The following extra format sequences (see [StrLiterals](https://github.com/JuliaString/StrLiterals.jl) for the full specification) are added:
 
-* `\%<ccc><formatcode>(arguments)` is interpolated as a call to `cfmt("<cccc><formatcode>",arguments)`, where `<ccc><formatcode>` is a C-style format string.

+* `\%(value, arguments...)` is interpolated as a call to `fmt(value, arguments...)`.
 This is especially useful when defaults have been set for the type of the first argument.
 
 * `fmt_default!{T}(::Type{T}, syms::Symbol...; kwargs...)` sets the defaults for a particular type.
 * `fmt_default!(syms::Symbol...; kwargs...)` sets the defaults for all types.
+* `reset!{T}(::Type{T})` resets the defaults for a particular type.
+* `defaultSpec(x)` will return the defaults for the type of x, and
+* `defaultSpec{T}(::Type{T})` will return the defaults for the given type.
 
 Symbols that can currently be used are: `:ljust` or `:left`, `:rjust` or `:right`, `:center`, `:commas`, `:zpad` or `:zeropad`, and `:ipre` or `:prefix`.
 Several keyword arguments can also be used:
