LicenseText makes a license text ready for analysis.

Relax applies very aggressive normalization rules to text.

Split applies heuristics to split the text into several parts.

Enforced is the strictest mode - only the official SPDX guidelines are applied.

Moderate is equivalent to Enforced with some additional normalization: dots are removed, copyright lines too.

Relaxed is the most powerful normalization, Moderate + Unicode normalization and all non-alphanumeric chars removed.

Strictness represents the aggressiveness of the performed normalization.
