.LP


.SH Modules extending some standard modules
.LP

.LP

* `logging_ext`, extensions to `logging` module such as a colorized formatter and an easier initialization function.
.LP

.LP


.SH Modules extending some external modules
.LP

* `corbautils`, useful functions for use with the OmniORB_ CORBA library.
.LP

.LP

* `vcgutils` , utilities functions to generate file readable with Georg Sander's vcg tool (Visualization of Compiler Graphs).
.LP


.SH To be deprecated modules
.LP

These `logilab.common` modules will probably be deprecated in future versions:
.LP

* `testlib`: use `unittest2`_ instead
.LP
* `pytest`: use `discover`_ instead
.LP
* `interface`: use `zope.interface`_ if you really want this
.LP
* `table`, `xmlutils`: is that used?
.LP
* `sphinxutils`: we won't go that way imo (i == syt)
.LP


.SH Deprecated modules
.LP

These `logilab.common` modules are only for backward compatibility. They can go away at anytime.
.LP

* `optparser`: use `clcommands` instead
.LP

* `adbh`, `db`, `sqlgen`: see `logilab.database`_ instead
.LP

* `contexts`: content move to `shellutils`
.LP

* `html`: deprecated without replacement
