+=head1 NAME
+
+PLP::Fields - Special hashes for PLP
+
+=head1 DESCRIPTION
+
+For your convenience, PLP uses hashes to put things in. Some of these are tied
+hashes, so they contain a bit magic. For example, building the hash can be
+delayed until you actually use the hash.
+
+=over 10
+
+=item C<%get> and C<%post>
+
+These are built from the C<key=value&key=value> (or C<key=value;key=value>
+strings in query string and post content. C<%post> is not built if the content
+type is not C<application/x-www-form-urlencoded>. In post content, the
+semi-colon is not a valid separator.
+
+%post isn't built until it is used, to speed up your script if you
+don't use it. Because POST content can only be read once, you can C<use CGI;>
+and just never access C<%post> to avoid its building.
+
+With a query string of C<key=firstvalue&key=secondvalue>, C<$get{key}> will
+contain only C<secondvalue>. You can access both elements by using the array
+reference C<$get{'@key'}>, which will contain C<[ 'firstvalue', 'secondvalue'
+]>.
+
+=item C<%fields>
+
+This hash combines %get and %post, and triggers creation of %post. POST gets
+precedence over GET (note: not even the C<@>-keys contain both values).
+
+This hash is built on first use, just like %post.
+
+=item C<%cookie>, C<%cookies>
+
+This is built immediately, because cookies are usually short in length. Cookies
+are B<not> automatically url-decoded.
+
+=item C<%header>, C<%headers>
+
+In this hash, you can set headers. Underscores are converted to normal minus
+signs, so you can leave out quotes. The hash is case insensitive: the case used
+when sending the headers is the one you used first. The following are equal:
+
+ $header{CONTENT_TYPE}
+ $header{'Content-Type'}
+ $header{Content_Type}
+ $headers{CONTENT_type}
