dnl (the pretty numbers that the users see)

dnl Interface version details for libtool
dnl ================================================================
# Note: we don't automatically deduce the libtool version info from
# the pretty version number that users sees. This is because we want
# to update the pretty version number before making a release since it
# can affect the name of our pkg-config file and the naming or
# location of other installed files which we want to be able to verify
# as correct well before making a release.
#
# For reference on how the various numbers should be updated at
# release time these rules are adapted from the libtool info pages:
#
# 1. Update the version information only immediately before a public
# release.
#
# 2. If the library source code has changed at all since the last
# update, then increment REVISION (`C:R:A' becomes `C:r+1:A').
#
# 3. If any interfaces have been added, removed, or changed since the
# last update, increment CURRENT, and set REVISION to 0.
#
# 4. If any interfaces have been added since the last public release,
# then increment AGE.
#
# 5. If any interfaces have been removed since the last public release,
# then set AGE to 0.
