+/**
+ * Function that returns two types of paths, one relative to symlink, and one
+ * relative to the current working directory. Checks if path is absolute or
+ * relative. If the path is relative, this function checks if the path is
+ * relative to symlink or relative to current working directory. This is an
+ * initiative to find a smarter `srcpath` to supply when building symlinks.
+ * This allows you to determine which path to use out of one of three possible
+ * types of source paths. The first is an absolute path. This is detected by
+ * `path.isAbsolute()`. When an absolute path is provided, it is checked to
+ * see if it exists. If it does it's used, if not an error is returned
+ * (callback)/ thrown (sync). The other two options for `srcpath` are a
+ * relative url. By default Node's `fs.symlink` works by creating a symlink
+ * using `dstpath` and expects the `srcpath` to be relative to the newly
+ * created symlink. If you provide a `srcpath` that does not exist on the file
+ * system it results in a broken symlink. To minimize this, the function
+ * checks to see if the 'relative to symlink' source file exists, and if it
+ * does it will use it. If it does not, it checks if there's a file that
+ * exists that is relative to the current working directory, if does its used.
+ * This preserves the expectations of the original fs.symlink spec and adds
+ * the ability to pass in `relative to current working direcotry` paths.
