.BI "void ego(const char *" p );
.B "const char *quis(void);"
.B "const char *QUIS;"

.SH DESCRIPTION
The
.B ego
function should be called early in your program's initialization
sequence, with the value of
.B argv[0]
as its argument.  It will strip away leading path components, and a
leading `\-' character (in case the program was called as a login
shell), and keep the resulting short name for later.
.PP
The
.B quis
function returns the stored program name.  There is also a macro
.B QUIS
which expands to the name of a global variable whose value is the string
returned by
.BR quis() .
.PP
Don't ask why it's done this way.  There are raisins, but they're mostly
hysterical.
.PP
The program name is used in the messages produced by the
.BR die (3)
and
.BR moan (3)
functions.
.SH "SEE ALSO"
.BR report (3),
.BR mLib (3).
