This is GNU libtool, a generic library support script. Libtool hides the complexity of using shared libraries behind a consistent interface. To use libtool, add the new generic library building commands to your Makefile, Makefile.in, or Makefile.am. See the documentation for details. Libtool supports building static libraries on all platforms. Shared library support has been implemented for these platforms: All ELF targets that use both the GNU C compiler (gcc) and GNU ld AIX 3.x (*-*-aix3*) AIX 4.x (*-*-aix4*) Digital/UNIX 3.x, 4.x, a.k.a. OSF/1 (*-*-osf3*, *-*-osf4*) FreeBSD 2.x, 3.x (*-*-freebsd2*, *-*-freebsd3*) HP-UX 9.x, 10.x (*-*-hpux9*, *-*-hpux10*) IRIX 5.x, 6.x (*-*-irix5*, *-*-irix6*) Linux ELF (*-*-linux*, except aout, coff, and oldld) NetBSD 1.x (*-*-netbsd*) OpenBSD 2.x (*-*-openbsd*) SCO OpenServer 5.x (*-*-sco3.2v5*) Solaris 2.x (*-*-solaris2*) SunOS 4.x, a.k.a. Solaris 1.x (*-*-sunos4*) See the file NEWS for a description of recent changes to libtool. See the file INSTALL for instructions on how to build and install libtool. See the info node (libtool)Tested Platforms. (or the file doc/platforms.texi) for a list of platforms that libtool shared library support was tested on. If you have any suggestions or bug reports, or you wish to port libtool to a new platform, please send electronic mail to the libtool mailing list . Don't forget to mention the version of libtool that you are currently using (by typing `ltconfig --version').
