[gcompris-devel] Applying as a student for GSoC

Wed Apr 6 17:42:06 UTC 2011

Hi,

This is the small bug fix I made in the Hydroelectric activity.
The Bug : https://bugzilla.gnome.org/show_bug.cgi?id=640157
Proposed Patch :
https://bugzilla.gnome.org/attachment.cgi?id=185343&action=edit

The word 'meter' which meant the instrument occurs which was ambiguous with
the measurement unit meter. This confuses a few translator as mentioned in
the bug report. Thus I have changed it to "The meter is used to measure ...
" thus depicting it is a measuring instrument.

Thanks a lot,
