Reqtrace is a package for simple request tracing. it requires nothing of its user except:

* they must use golang.org/x/net/context. * they must add a single line to each function they want to be visible in
traces.
in particular, reqtrace is console-based and doesn't require an http server.

warning: this package is still barebones and in its early days. the author reserves the right to make backwards-incompatible changes to its api. but if it's useful to you in your current form, have at it.
