+%%% Module Description
+%%% ------ -----------
+%%% ts Frontend to the test server framework. Contains all
+%%% interface functions.
+%%% ts_install Installs the test suite. On Unix, `autoconf' is
+%%% is used; on Windows, ts_autoconf_win32 is used,
+%%% on VxWorks, ts_autoconf_vxworks is used.
+%%% The result is written to the file `variables'.
+%%% ts_run Supervises running of the tests.
+%%% ts_autconf_win32 An `autoconf' for Windows.
+%%% ts_autconf_cross_env `autoconf' for other platforms (cross environment)
+%%% ts_erl_config Finds out information about the Erlang system,
+%%% for instance the location of erl_interface.
+%%% This works for either an installed OTP or an Erlang
+%%% system running from Clearcase.
+%%% ts_make Interface to run the `make' program on Unix
+%%% and other platforms.
+%%% ts_make_erl A corrected version of the standar Erlang module
+%%% make (used for rebuilding test suites).
+%%% ts_reports Generates index pages in HTML, providing a summary
+%%% of the tests run.
+%%% ts_lib Miscellanous utility functions, each used by several
+%%% other modules.
