// 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.
