# Before making a release, the LT_VERSION string should be modified.
# See: http://www.gnu.org/software/libtool/manual.html#Versioning
#
# The string is of the form Current:Revision:Age.
#
# The following lines are taken from the GNU Libtool Manual:
# Here are a set of rules to help you update your library version information:
#
# Start with version information of 0:0:0 for each libtool library.
# 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.
#
# 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 since the last public release, then set age to 0.
#
# Never try to set the interface numbers so that they correspond to the release number of your package.
# This is an abuse that only fosters misunderstanding of the purpose of library versions. Instead,
# use the -release flag (see Release numbers), but be warned that every release of your package will
# not be binary compatible with any other release.
