Finding Files Relative to the Source File in Go

Unlike interpreted languages, Go programs are compiled and the source file is not required for execution. Therefore, the concept of locating files relative to the source file, as seen in Ruby with __FILE__, is not applicable in Go.

Instead, Go provides the runtime.Caller function, which returns the filename at the time of compilation. However, this information is not always useful for dynamically locating files.
