ldd -- list dynamic object dependencies
ldd [-a] [-v] [-f format] program ...
The ldd utility displays all shared objects that are needed to run the
given program or to load the given shared object. Contrary to nm(1), the
list includes ``indirect'' dependencies that are the result of needed
shared objects which themselves depend on yet other shared objects.
Zero, one or two -f options may be given. The argument is a format
string passed to rtld(1) and allows customization of ldd's output. See
rtld(1) for a list of recognized conversion characters.
The -a option displays the list of all objects that are needed by each
loaded object. This option does not work with a.out(5) binaries.
The -v option displays a verbose listing of the dynamic linking headers
encoded in the executable. See the source code and include files for the
definitive meaning of all the fields.

A ldd utility first appeared in SunOS 4.0, it appeared in its current
form in FreeBSD 1.1.
The -v support is based on code written by John Polstra <firstname.lastname@example.org>
