Please recommend a book on C++ regex

[dglatting]

Please recommend to me a book (paper and maybe an ebook) with depth on regular expression classes theory, implementation, usage, and examples in c++11.

I am a C++ hack but I have been away from coding for some years. I use regular expressions in my other day-to-day work from egrep, sh, awk, to C code.

Thanks, and pardon the dumb question. :)
