# Before making a release, the GDATA_LT_VERSION string should be modified. The string is of the form c:r:a. Follow these instructions sequentially:
#
#  1. If the library source code has changed at all since the last update, then increment revision (‘c:r:a’ becomes ‘c:r+1:a’).
#  2. If any interfaces have been added, removed, or changed since the last update, increment current, and set revision to 0.
#  3. If any interfaces have been added since the last public release, then increment age.
#  4. If any interfaces have been removed or changed since the last public release, then set age to 0.
#
# Note that versioning started at 2:0:0 to ensure no conflicts with e-d-s' libgdata library, whose maximum version was 1:0:0
