+This directory contains Python libraries for genome browser CGIs
+written in Python (e.g. hgGeneGraph). The ideal Python version is 2.7, but
+CentOs is at the time of writing on 2.6 so hgLib.py is avoiding any special 2.7
+features and uses the python2 in the hash bang line, so it will use whatever
+python2 version is available (2.7 on genome-asia/genome-euro and 2.6 on the RR, 
+at the time of writing).
+
+The directory is called pyLib because in the future, other libraries can be
+copied into this directory, it is likely that we will need more libraries, not
+only hgLib.py.
+
+hgLib.py includes various pieces of code ported from kent source hg/lib, like
+the bottleneck client, cart parsing, mysql functions, etc.
+
+The CGIs are not currently using a more efficient way of running Python scripts
+through Apache (WSGI), because this would be a considerable amount of administration
+across our various servers. It seems that running CGIs the "old" way is costing us
+only 100-200msecs so it is still bearable for the non-essential CGIs we may 
+have in Python.
