+Beta Phylogenetic Passthrough
+###############################################################
+
+Computes a distance matrix for all pairs of samples in a feature table
+using the unifrac implementation of the selected beta diversity metric.
+
+Parameters
+----------
+table : FeatureTable[Frequency]
+    The feature table containing the samples over which beta diversity
+    should be computed.
+phylogeny : Phylogeny[Rooted]
+    Phylogenetic tree containing tip identifiers that correspond to the
+    feature identifiers in the table. This tree can contain tip ids that
+    are not present in the table, but all feature ids in the table must be
+    present in this tree.
+metric : Str % Choices('unweighted_unifrac', 'generalized_unifrac', 'weighted_normalized_unifrac', 'weighted_unifrac')
+    The beta diversity metric to be computed.
+threads : Int % Range(1, None) | Str % Choices('auto'), optional
+    The number of CPU threads to use in performing this calculation. May
+    not exceed the number of available physical cores. If threads = 'auto',
+    one thread will be created for each identified CPU core on the host.
+variance_adjusted : Bool, optional
+    Perform variance adjustment based on Chang et al. BMC Bioinformatics
+    2011. Weights distances based on the proportion of the relative
+    abundance represented between the samples at a given node under
+    evaluation.
+alpha : Float % Range(0, 1, inclusive_end=True), optional
+    This parameter is only used when the choice of metric is
+    generalized_unifrac. The value of alpha controls importance of sample
+    proportions. 1.0 is weighted normalized UniFrac. 0.0 is close to
+    unweighted UniFrac, but only if the sample proportions are
+    dichotomized.
+bypass_tips : Bool, optional
+    In a bifurcating tree, the tips make up about 50% of the nodes in a
+    tree. By ignoring them, specificity can be traded for reduced compute
+    time. This has the effect of collapsing the phylogeny, and is analogous
+    (in concept) to moving from 99% to 97% OTUs
+
+Returns
+-------
+distance_matrix : DistanceMatrix
+    The resulting distance matrix.
