+Pycolib
+========
+
+Pycolib is library of small, mostly one-file, modules with little or not (inter)dependencies.
+
+ * ansicolor - change color of text in terminal using ANSI escape sequences
+ * makeurl - adjust string for using in URL by replacing symbols and combined unicode chars
+ * prettysize - print file sizes in human readable form
+ * soap - minimal SOAP client
