docs: Move wiki docs into Documentation dir Going forward, all documentation should be placed in the Documentation directory in the root of the project. This switch allows maintainers to approve updates to documentation before they are committed, as opposed to the pre-existing wiki which anybody could modify. Currently the Documentation directory includes docs on building, usage, and minimal docs around the API. This is just the initial commit, and documentation will continue to improve over time. Some changes have been made (and will continue to be made) to `cmd/dlv` to ensure we can auto-generate documentation for all commands from the newly provided script `scripts/gen-usage-docs.go`, which can be invoked via `go run scripts/gen-usage-docs.go`. Additionally, version has been split into its own package. This was a bit of housekeeping related to the changes made the `cmd/dlv`.

## dlv trace
Compile and begin tracing program.
### Synopsis
dlv/cmds: Improve subcommand help output
2016-05-20 17:51:23 +00:00
Trace program execution.
The trace sub command will set a tracepoint on every function matching the
provided regular expression and output information when tracepoint is hit. This
is useful if you do not want to begin an entire debug session, but merely want
to know what functions your process is executing.
