// Package sanitized_anchor_name provides a func to create sanitized anchor names.
//
// Its logic can be reused by multiple packages to create interoperable anchor names
// and links to those anchors.
//
// At this time, it does not try to ensure that generated anchor names
// are unique, that responsibility falls on the caller.
package sanitized_anchor_name // import "github.com/shurcooL/sanitized_anchor_name"
import "unicode"
// Create returns a sanitized anchor name for the given text.
