+"""Classes to generate HTML in Python
+
+The HTMLTags module defines a class for all the valid HTML tags, written in
+uppercase letters. To create a piece of HTML, the general syntax is :
+    t = TAG(inner_HTML, key1=val1,key2=val2,...)
+
+so that "print t" results in :
+    <TAG key1="val1" key2="val2" ...>inner_HTML</TAG>
+
+For instance :
+    print A('bar', href="foo") ==> <A href="foo">bar</A>
+
+To generate HTML attributes without value, give them the value True :
+    print OPTION('foo',SELECTED=True,value=5) ==> 
+            <OPTION value="5" SELECTED>
+
+The inner_HTML argument can be an instance of an HTML class, so that 
+you can nest tags, like this :
+    print B(I('foo')) ==> <B><I>foo</I></B>
+
+TAG instances support addition :
+    print B('bar')+INPUT(name="bar") ==> <B>bar</B><INPUT name="bar">
+
+and repetition :
+    print TH('&nbsp')*3 ==> <TD>&nbsp;</TD><TD>&nbsp;</TD><TD>&nbsp;</TD>
+
+For complex expressions, a tag can be nested in another using the operator <= 
+Considering the HTML document as a tree, this means "add child" :
+
+    form = FORM(action="foo")
+    form <= INPUT(name="bar")
+    form <= INPUT(Type="submit",value="Ok")
+
+If you have a list (or any iterable) of instances, you can't concatenate the 
+items with sum(instance_list) because sum takes only numbers as arguments. So 
+there is a function called Sum() which will do the same :
+
+    Sum( TR(TD(i)+TD(i*i)) for i in range(100) )
+
+generates the rows of a table showing the squares of integers from 0 to 99
+
+A simple document can be produced by :
+    print HTML( HEAD(TITLE('Test document')) +
+        BODY(H1('This is a test document')+
+             'First line'+BR()+
+             'Second line'))
+
+This will be rendered as :
+    <HTML>
+    <HEAD>
+    <TITLE>Test document</TITLE>
+    </HEAD>
+    <BODY>
+    <H1>This is a test document</H1>
+    First line
+    <BR>
+    Second line
+    </BODY>
+    </HTML>
+
+If the document is more complex it is more readable to create the elements 
+first, then to print the whole result in one instruction. For example :
+
+head = HEAD()
+head <= TITLE('Record collection')
+head <= LINK(rel="Stylesheet",href="doc.css")
+
+title = H1('My record collection')
+table = TABLE()
+table <= TR(TH('Title')+TH('Artist'))
+for rec in records:
+    row = TR()
+    # note the attribute key Class with leading uppercase 
+    # because "class" is a Python keyword
+    row <= TD(rec.title,Class="title")+TD(rec.artist,Class="artist")
+    table <= row
+
+print HTML(head+BODY(title+table))
