+=head1 NAME
+
+dtas-archive - paranoid audio file copy
+
+=head1 SYNOPSYS
+
+dtas-archive [OPTIONS] SOURCE DESTINATION
+
+=head1 DESCRIPTION
+
+dtas-archive is intended for archiving audio data to/from laptops,
+marginal USB ports, and computers without ECC memory, attempting
+to read data multiple times in an attempt to detect memory or
+bus corruption.  dtas-archive may only be effective on machines
+running the Linux kernel where L<posix_fadvise(2)> can be used to
+drop caches for a particular file after L<fsync(2)>.
+
+dtas-archive spawns L<sox(1)> to archive audio data (likely uncompressed
+WAVE) to FLAC and verifies the result using L<sndfile-cmp(1)>, a tool
+implemented by different than sox and less likely to share the same bugs
+(if any) as sox.
