This - is what `freetype-config --version' returns. - - * The platform-specific shared object number, used for example when - the library is installed as `/usr/lib/libfreetype.so.6.7.1'. - -The platform-specific number is, unsurprisingly, platform-specific and -varies with the operating system you are using (several variants of -Linux, FreeBSD, Solaris, etc.).
