 Also, Unicode sequences are represented as in Swift, i.e. as `\u{hexdigits}`, where there
 can be from 1 to 6 hex digits. This syntax eliminates having to worry about always outputting
 4 or 8 hex digits, to prevent problems with 0-9,A-F,a-f characters immediately following.
-Finally, I have added two new ways of representing characters in the literal string,
-`\:emojiname:` and `\{latexname}`.
+Finally, I have added four ways of representing characters in the literal string,
+`\:emojiname:`, `\<latexname>`, `\&htmlname;` and `\N{UnicodeName}`.
 This makes life a lot easier when you want to keep the text of a program in ASCII, and
 also to be able to write programs using those characters that might not even display
 correctly in their editor.
 
 This now has some initial formatting capability, based on Tom Breloff's wonderful PR #10 to the
 JuliaLang/Formatting.jl package (by Dahua Lin and other contributors).
+
 `\%(arguments)` is interpolated as a call to fmt(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.
+Symbols that can currently be used are: `:ljust` or `:left`, `:rjust` or `:right`, `:commas`,
+`:zpad` or `:zeropad`, and `:ipre` or `:prefix`.
+`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.
 
-I also plan on adding support for `\%c(arguments)`, where c is a C style formatting character.
-I'm debating if I should make it take the full C style syntax, with leading 0, width/precision,
-etc, before the single character.
+This also adds support for `\%ccc(arguments)`, where ccc is one or more characters of a
+single C style format specification, which is interpolated as a call to cfmt("ccc", arguments).
 
+I'm also experimenting with adding Python style syntax (as much as possible), as
+u"\{pythonformat}"
