.SH DESCRIPTION
.sp
krb5\-config tells the application programmer what flags to use to compile
and link programs against the installed Kerberos libraries.
.SH OPTIONS

.TP
\fB\-\fP\fB\-version\fP
prints the version number of the Kerberos installation.
.TP
\fB\-\fP\fB\-vendor\fP
prints the name of the vendor of the Kerberos installation.
.TP
\fB\-\fP\fB\-prefix\fP
prints the prefix for which the Kerberos installation was built.
.TP
\fB\-\fP\fB\-exec\-prefix\fP
prints the prefix for executables for which the Kerberos installation
was built.
.TP
\fB\-\fP\fB\-defccname\fP
prints the built\-in default credentials cache location.
.TP
\fB\-\fP\fB\-defktname\fP
prints the built\-in default keytab location.

\fB\-\fP\fB\-defcktname\fP
prints the built\-in default client (initiator) keytab location.
.TP
\fB\-\fP\fB\-cflags\fP
prints the compilation flags used to build the Kerberos installation.
.TP
\fB\-\fP\fB\-libs\fP [\fIlibrary\fP]
prints the compiler options needed to link against \fIlibrary\fP\&.

.SH EXAMPLES
.sp
krb5\-config is particularly useful for compiling against a Kerberos
installation that was installed in a non\-standard location.  For example,
a Kerberos installation that is installed in \fB/opt/krb5/\fP but uses
libraries in \fB/usr/local/lib/\fP for text localization would produce
the following output:
.INDENT 0.0
.INDENT 3.5
