/**
 * Utility to rename weight files to matching alignment basenames.
 * Usage: java -cp goby.jar edu.cornell.med.icb.goby.util.RenameWeights *XXX.gc-weights
 * The previous line will copy each XXX/match/.gc-weight to the alignment basename
 * that matches XXX and ends with .entries.  For instance, the file XXX.gc-weights
 * will be renamed 1212-XXX.gc-weights if an alignment file named 1212-XXX.entries exists.
