+single-cell or bulk RNA-seq data, which can be directly used for donor
+deconvolution in multiplexed single-cell RNA-seq data, particularly with other
+packages, which assigns cells to donors and detects doublets as vireo, even
+without genotyping reference.
+
+This package is the C version of the deprecated cellSNP implemented in Python.
+Compared to cellSNP, this package is more efficient with higher speed and less
+memory usage.")
