# SECTION 2: Configure script command line options
# Updating library version information
# ==========================================================================================================
# If you want to use libtool's versioning system, then you must specify the version information to libtool
# using the `-version-info' flag during link mode (Note: Link mode)
#
# This flag accepts an argument of the form `CURRENT[:REVISION[:AGE]]'. So, passing `-version-info 3:12:1' sets CURRENT to 3, REVISION to 12, and AGE to 1
#
# If either REVISION or AGE are omitted, they default to 0. Also note that AGE must be less than or equal to the CURRENT interface number.
#
# Here are a set of rules to help you update your library version information:
#
# 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.
#
# *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 (Note: Release numbers), but be warned
# that every release of your package will not be binary compatible with any other release.
# ==========================================================================================================
# By default, this macro turns on shared libraries if they are available, and also enables static libraries
# if they don't conflict with the shared libraries. You can modify these defaults by calling either the
# `AC_DISABLE_SHARED' or `AC_DISABLE_STATIC' macros:
