*{project}* is a search tool for EPUB e-books. It does not operate on lines, but
on whole files. All newlines will be replaced by spaces and HTML will be
stripped. This means you can search for text spanning multiple lines and don't
have to worry about HTML tags in the text.

{project} is licensed under the link:{license}[AGPL-3.0-only]. The bundled
link:{uri-termcolor}[Termcolor] is licensed under the
link:{license-termcolor}[BSD-3-Clause] license.
