)These flags define which text to prefix to each log entry generated by the Logger. Bits are or'ed together to control what's printed. There is no control over the order they appear (the order listed here) or the format they present (as described in the comments). The prefix is followed by a colon only if more than time is stated is specified. For example, flags Ldate | Ltime produce, 2009/01/23 01:23:23 message. The standard is: 2009/01/23 01:23:23 ...a/logger/c/d.go:23:runtime.Caller() [I]: message

Register registers given logger provider to providers.
Stack will skip back the provided number of frames and return a stack trace with source code. Although we could just use debug.Stack(), this routine will return the source code and skip back the provided number of frames - i.e. allowing us to ignore preceding function calls. A skip of 0 returns the stack trace for the calling function, not including this call. If the problem is a lack of memory of course all this is not going to work...
