+
+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

+
+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

+Generates a hidden field, used to pass data to the script without

+

+

+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
