-
-Simple profiling support package for Go
-
-[![Build Status](https://travis-ci.org/pkg/profile.svg?branch=master)](https://travis-ci.org/pkg/profile) [![GoDoc](http://godoc.org/github.com/pkg/profile?status.svg)](http://godoc.org/github.com/pkg/profile)
-
-
-installation
-------------
-
-    go get github.com/pkg/profile
-
-usage
------
-
-Enabling profiling in your application is as simple as one line at the top of your main function
-
-```go
-import "github.com/pkg/profile"
-
-func main() {
-    defer profile.Start().Stop()
-    ...
-}
-```
-
-options
--------
-
-What to profile is controlled by config value passed to profile.Start. 
-By default CPU profiling is enabled.
-
-```go
-import "github.com/pkg/profile"
-
-func main() {
-    // p.Stop() must be called before the program exits to
-    // ensure profiling information is written to disk.
-    p := profile.Start(profile.MemProfile, profile.ProfilePath("."), profile.NoShutdownHook)
-    ...
-}
-```
-
-Several convenience package level values are provided for cpu, memory, and block (contention) profiling.
-
-For more complex options, consult the [documentation](http://godoc.org/github.com/pkg/profile).
-
-contributing
-------------
-
-We welcome pull requests, bug fixes and issue reports.
-
-Before proposing a change, please discuss it first by raising an issue.
