%description
Implementations of several methods for principal component analysis using
the L1 norm.  The package depends on COIN-OR Clp version >= 1.17.4.  The
methods implemented are PCA-L1 (Kwak 2008) <DOI:10.1109/TPAMI.2008.114>,
L1-PCA (Ke and Kanade 2003, 2005) <DOI:10.1109/CVPR.2005.309>, L1-PCA*
