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.

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.

To minimize this, the function+ * checks to see if the 'relative to symlink' source file exists, and if it+ * does it will use it.
