=head2 Main functions
The following functions are exported by default when using C<OpenSSL::Test>.

-=item B<app ARRAYREF, OPTS>
-
-=item B<test ARRAYREF, OPTS>
-
-Both of these functions take a reference to a list that is a command and
-its arguments, and some additional options (described further on).
-
-C<app> expects to find the given command (the first item in the given list
-reference) as an executable in C<$BIN_D> (if defined, otherwise C<$TOP/apps>
-or C<$BLDTOP/apps>).
+=item B<cmd ARRAYREF, OPTS>
-C<test> expects to find the given command (the first item in the given list
-reference) as an executable in C<$TEST_D> (if defined, otherwise C<$TOP/test>
-or C<$BLDTOP/test>).
+This functions build up a platform dependent command based on the
+input. It takes a reference to a list that is the executable or
+script and its arguments, and some additional options (described
+further on). Where necessary, the command will be wrapped in a
+suitable environment to make sure the correct shared libraries are
+used (currently only on Unix).
-Both return a CODEREF to be used by C<run>, C<pipe> or C<cmdstr>.
+It returns a CODEREF to be used by C<run>, C<pipe> or C<cmdstr>.

+=item B<app ARRAYREF, OPTS>
+
+=item B<test ARRAYREF, OPTS>
+
+Both of these are specific applications of C<cmd>, with just a couple
+of small difference:
+
+C<app> expects to find the given command (the first item in the given list
+reference) as an executable in C<$BIN_D> (if defined, otherwise C<$TOP/apps>
+or C<$BLDTOP/apps>).
+
+C<test> expects to find the given command (the first item in the given list
+reference) as an executable in C<$TEST_D> (if defined, otherwise C<$TOP/test>
+or C<$BLDTOP/test>).
+
+Also, for both C<app> and C<test>, the command may be prefixed with
+the content of the environment variable C<$EXE_SHELL>, which is useful
+in case OpenSSL has been cross compiled.
+
=item B<perlapp ARRAYREF, OPTS>
=item B<perltest ARRAYREF, OPTS>
-Both these functions function the same way as B<app> and B<test>, except
-that they expect the command to be a perl script. Also, they support one
-more option:
+These are also specific applications of C<cmd>, where the interpreter
+is predefined to be C<perl>, and they expect the script to be
+interpreted to reside in the same location as C<app> and C<test>.
+
+C<perlapp> and C<perltest> will also take the following option:
=over 4
=item B<interpreter_args =E<gt> ARRAYref>
-The array reference is a set of arguments for perl rather than the script.
-Take care so that none of them can be seen as a script! Flags and their
-eventual arguments only!

+=begin comment
+
+One might wonder over the complexity of C<apps>, C<fuzz>, C<test>, ...
+with all the lazy evaluations and all that. The reason for this is that
+we want to make sure the directory in which those programs are found are
+correct at the time these commands are used. Consider the following code
+snippet:
+
+ my $cmd = app(["openssl", ...]);
+
+ indir "foo", sub {
+ ok(run($cmd), "Testing foo")
+ };
+
+If there wasn't this lazy evaluation, the directory where C<openssl> is
+found would be incorrect at the time C<run> is called, because it was
+calculated before we moved into the directory "foo".
