+"""
+Create Sphinx documentation. Currently only LaTeX and HTML are supported.
+
+The source file **must** be the conf.py file used by Sphinx. Everything
+else has defaults, passing in the parameters is optional.
+
+Usage for getting both html and pdf docs:
+
+    ctx(features='sphinx', source='docs/conf.py')
+    ctx(features='sphinx', source='docs/conf.py', buildername='latex')
+
+Optional parameters and their defaults:
+
+    * buildername: html
+    * srcdir: confdir (the directory where conf.py lives)
+    * outdir: confdir/buildername (in the build directory tree)
+    * doctreedir: outdir/.doctrees
+    * type: pdflatex (only applies to 'latex' builder)
