+/* alignfiles.h -- perform alignment given filenames
+ *
+ * this module is an intermediate between the command-line interface 
+ * main.cpp and the alignment code in scorealign.cpp. The scorealign.cpp
+ * module is supposed to work on data from any source, e.g. it could be
+ * a file, or it could be an object that sucks samples out of an
+ * Audacity wave track. This module is supposed to not assume a command
+ * line, type-script based interface, but *does* assume that you want
+ * to read data from files, so you pass filenames into this module and
+ * it reads the files and calls scorealign.cpp to do the alignment work.
