+works with any @code{net/http} based stdlib implementation.  Inspired by the
+Node @code{nock} library, it has features like:
+@itemize
+@item Simple and expressive API
+@item Semantic API DSL for declarative HTTP mock declarations
+@item Built-in helpers for easy JSON/XML mocking
+@item Supports persistent and volatile TTL-limited mocks
+@item Full regular expressions capable HTTP request mock matching
+@item Designed for both testing and runtime scenarios
+@item Match request by method, URL params, headers and bodies
+@item Extensible and pluggable HTTP matching rules
+@item Ability to switch between mock and real networking modes
+@item Ability to filter/map HTTP requests for accurate mock matching
+@item Supports map and filters to handle mocks easily
+@item Wide compatible HTTP interceptor using @code{http.RoundTripper} interface
+@item Works with any @code{net/http} compatible client, such as @code{gentleman}
+@item Network timeout/cancelation delay simulation
+@item Extensible and hackable API
