.SS "Display of algorithm names"
.IX Subsection "Display of algorithm names"
Algorithm names may be displayed in one of two manners:
.IP "Legacy implementations" 4
.IX Item "Legacy implementations"
Legacy implementations will simply display the main name of the
algorithm on a line of its own, or in the form \f(CW\*(C`<foo \*(C'\fR bar>> to show
that \f(CW\*(C`foo\*(C'\fR is an alias for the main name, \f(CW\*(C`bar\*(C'\fR
.IP "Provided implementations" 4
.IX Item "Provided implementations"
Implementations from a provider are displayed like this if the
implementation is labeled with a single name:
.Sp
.Vb 1
\& foo @ bar
.Ve
.Sp
or like this if it's labeled with multiple names:
.Sp
.Vb 1
\& { foo1, foo2 } @bar
.Ve
.Sp
In both cases, \f(CW\*(C`bar\*(C'\fR is the name of the provider.
