-Finds a directory containing the desired template. The C<template>
-argument specifies the template you're looking for (this should be the
-name of the script you're using to generate an HTML page, without the
-C<.pl> extension). Only the C<template> argument is required; the
-others are optional.
-
-C<theme> specifies the name of the theme to use. This will be used
-only if it is allowed by the C<allowthemeoverride> system preference
-option (in the C<systempreferences> table of the Koha database).
-
-C<language> specifies the desired language. If not specified,
-C<&pathtotemplate> will use the list of acceptable languages 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<&pathtotemplate> searches first in the directory given by the
-C<path> argument, if any, then in the directories given by the
-C<templatedirectory> and C<includes> directives in F</etc/koha.conf>,
-in that order.
-
-C<&pathtotemplate> returns a hash with the following keys:
-
-=over 4
-
-=item C<path>
-
-The full pathname to the desired template.
-
-=item C<foundlanguage>
-
-The value is set to 1 if a template in the desired language was found,
-or 0 otherwise.
-
-=item C<foundtheme>
-
-The value is set to 1 if a template of the desired theme was found, or
-0 otherwise.
-
-=back
-
-If C<&pathtotemplate> cannot find an acceptable template, it returns 0.
-
-Note that if a template of the desired language or theme cannot be
-found, C<&pathtotemplate> will print a warning message. Unless you've
-set C<$SIG{__WARN__}>, though, this won't show up in the output HTML
-document.

-C<$action> is the action for the form, usually the URL of the script

-
-The remaining arguments define the fields in the form. C<$fieldname>

-C<$fieldpos> is an integer; fields will be output in order of

-

-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.

-Generates a pair of radio buttons, with values C<$fieldvalue> and
-C<$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
