+=head1 NAME
+
+Font::TTF::PCLT - PCLT TrueType font table
+
+=head1 DESCRIPTION
+
+The PCLT table holds various pieces HP-PCL specific information. Information
+here is generally not used by other software, except for the xHeight and
+CapHeight which are stored here (if the table exists in a font).
+
+=head1 INSTANCE VARIABLES
+
+Only from table and the standard:
+
+    version
+    FontNumber
+    Pitch
+    xHeight
+    Style
+    TypeFamily
+    CapHeight
+    SymbolSet
+    Typeface
+    CharacterComplement
+    FileName
+    StrokeWeight
+    WidthType
+    SerifStyle
+
+Notice that C<Typeface>, C<CharacterComplement> and C<FileName> return arrays
+of unsigned characters of the appropriate length
