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.

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.
