# set the libtool versioning
# Quick guide into libtool versioning:
# 1. Start with version information of `0:0:0' for each libtool library.
# 2. Update the version information only immediately before a public release of your software. 
#    More frequent updates are unnecessary, and only guarantee that the current interface number 
#    gets larger faster.
# 3. If the library source code has changed at all since the last update, then increment revision 
#    (`c:r:a' becomes `c:r+1:a').
# 4. If any interfaces have been added, removed, or changed since the last update, 
#    increment current, and set revision to 0.
# 5. If any interfaces have been added since the last public release, then increment age.
# 6. If any interfaces have been removed since the last public release, then set age to 0.
