.\"O .B ldconfig
.\"O creates the necessary links and cache (for use by the run-time linker,
.\"O .IR ld.so )
.\"O to the most recent shared libraries found in the directories specified
.\"O on the command line, in the file
.\"O .IR /etc/ld.so.conf ,
.\"O and in the trusted directories
.\"O .RI ( /usr/lib
.\"O and
.\"O .IR /lib ).

.\"O will attempt to deduce the type of ELF libs (ie. libc5 or libc6/glibc)
.\"O based on what C libs if any the library was linked against, therefore when
.\"O making dynamic libraries, it is wise to explicitly link against libc (use -lc).

.\"O Some existing libs do not contain enough information to allow the deduction of 
.\"O their type, therefore the 
.\"O .IR /etc/ld.so.conf 
.\"O file format allows the specification of an expected type.  This is 
.\"O .B only
.\"O used for those ELF libs which we can not work out. The format 
.\"O is like this "dirname=TYPE", where type can be libc4, libc5 or libc6.
.\"O (This syntax also works on the command line).  Spaces are 
.\"O .B not 
.\"O allowed.  Also see the 
.\"O .B -p 
.\"O option.
