%description
Implements a fast and resistant divisive clustering algorithm which
identifies a specified number of clusters: 'lumbermark' iteratively chops
off sizeable limbs that are joined by protruding segments of a dataset's
mutual reachability minimum spanning tree; see Gagolewski (2026)
<https://lumbermark.gagolewski.com/>. The use of a mutual reachability
distance pulls peripheral points farther away from each other.  When
combined with the 'deadwood' package, it can act as an outlier detector.
The 'Python' version of 'lumbermark' is available via 'PyPI'.
