A ppx rewriter that defines extension nodes for logging: primarily useful
to avoid the allocation of sexps that will never be logged.

[%log.debug log "example log" (content : Content.t)]
[%log.global.debug "example log" (content : Content.t)]

How to add to your project

First, add ppx_log to your jbuild:

(preprocess (pps (ppx_jane ... ppx_log)))

If you have an import.ml file, then add include Ppx_log_async to use ppx_log
with Async.Log. Otherwise, you can simply open Ppx_log_async in the files that you
want to log.

Finally [%log.debug] to your heart's content!
