%%%
%%% 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 in a git repository/source tree.
%%% 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.
