%description
Read and write labelled sparse matrices in text format as used by software
such as 'SVMLight', 'LibSVM', 'ThunderSVM', 'LibFM', 'xLearn', 'XGBoost',
'LightGBM', and others. Supports labelled data for regression,
classification (binary, multi-class, multi-label), and ranking (with 'qid'
field), and can handle header metadata and comments in files.
