+=head1 NAME
+
+s2p.t - test suite for s2p/psed
+
+=head1 NOTES
+
+The general idea is to
+
+  (a) run psed with a sed script and input data to obtain some output
+  (b) run s2p with a sed script creating a Perl program and then run the
+      Perl program with the input data, again producing output
+
+Both final outputs should be identical to the expected output.
+
+A $testcase{<name>} contains entries (after the comment ### <name> ###):
+
+  - script: the sed script
+  - input:  the key of the input data, stored in $input{<input>}
+  - expect: the expected output
+  - datfil: an additional file [ <path>, <data> ] (if required)
+
+Temporary files are created in the working directory (embedding $$
+in the name), and removed after the test.
+
+Except for bin2dec (which indeed converts binary to decimal) none of the
+sed scripts is doing something useful.
+
+Author: Wolfgang Laun.
