+C<theme> specifies the name of the theme to use. This will be used

+option (in the C<systempreferences> table of the Koha database).

+C<language> specifies the desired language. If not specified,

+by the browser, then C<all>, and finally C<en> as fallback options.
+
+C<type> may be C<intranet>, C<opac>, C<none>, or some other value.
+C<intranet> and C<opac> specify that you want a template for the
+internal web site or the public OPAC, respectively. C<none> specifies
+that the template you're looking for is at the top level of one of the
+include directories. Any other value is taken as-is, as a subdirectory
+of one of the include directories.
+
+C<path> specifies an include directory.
+

+C<path> argument, if any, then in the directories given by the
+C<templatedirectory> and C<includes> directives in F</etc/koha.conf>,

+
+The remaining arguments define the fields in the form. C<$fieldname>
+is the field's name. This is for the script's benefit, and will not be
+shown to the user.
+
+C<$fieldpos> is an integer; fields will be output in order of
+increasing C<$fieldpos>. This number must be unique: if two fields
+have the same C<$fieldpos>, one will be picked at random, and the
+other will be ignored. See below for special considerations, however.

+the following:

+
+=item C<hidden>
+
+Generates a hidden field, used to pass data to the script without
+showing it to the user. C<$fieldvalue> is the value.

+C<$fieldpos>. In both cases, C<$fieldvalue> and C<$fieldpos> will be
+shown to the user.
+
+=item C<text>
+
+Generates a one-line text input field. It initially contains
+C<$fieldvalue>.
+
+=item C<textarea>
+
+Generates a four-line text input area. The initial text (which, of
+course, may not contain any tabs) is C<$fieldvalue>.
+
+=item C<select>
+
+Generates a list of items, from which the user may choose one. This is
+somewhat different from other input field types, and should be
+specified as:
+ "myselectfield" => "select\t<label0>\t<text0>\t<label1>\t<text1>...",
+where the C<text>N strings are the choices that will be presented to
+the user, and C<label>N are the labels that will be passed to the
+script.
+
+However, C<text0> should be an integer, since it will be used to
+determine the order in which this field appears in the form. If any of
+the C<label>Ns are empty, the rest of the list will be ignored.

+ print $str;
+
+Takes a set of arguments that define an input form, generates an HTML
+string for the form, and returns the string.
+
+C<$action> is the action for the form, usually the URL of the script
+that will process it.
+
+The remaining arguments define the fields in the form. C<$fieldname>
+is the field's name. This is for the script's benefit, and will not be
+shown to the user.
+
+C<$fieldpos> is an integer; fields will be output in order of
+increasing C<$fieldpos>. This number must be unique: if two fields
+have the same C<$fieldpos>, one will be picked at random, and the
+other will be ignored. See below for special considerations, however.
+
+If C<$required> is the string C<R>, then the field is required, and
+the label will have C< (Req.)> appended.
+
+C<$label> is a string that will appear next to the input field.
+
+C<$fieldtype> specifies the type of the input field. It may be one of
+the following:
+
+=over 4
+
+=item C<hidden>
+
+Generates a hidden field, used to pass data to the script without
+showing it to the user. C<$value0> is its value.
+
+=item C<radio>
+
+Generates a pair of radio buttons, with values C<$value0> and
+C<$value1>. In both cases, C<$value0> and C<$value1> will be shown to
+the user, next to the radio button.
+
+=item C<text>
+
+Generates a one-line text input field. Its size may be specified by
+C<$value0>. The default is 40. The initial text of the field may be
+specified by C<$value1>.
+
+=item C<textarea>
+
+Generates a text input area. C<$value0> may be a string of the form
+"WWWxHHH", in which case the text input area will be WWW columns wide
+and HHH rows tall. The size defaults to 40x4.
+
+The initial text (which, of course, may not contain any tabs) may be
+specified by C<$value1>.
+
+=item C<select>
+
+Generates a list of items, from which the user may choose one. Here,
+C<$value1>, C<$value2>, etc. are a list of key-value pairs. In each
+pair, the key specifies an internal label for a choice, and the value
+specifies the description of the choice that will be shown the user.
+
+If C<$value0> is the same as one of the keys that follows, then the
+corresponding choice will initially be selected.
