     "This package provides the timing functions @code{tic} and @code{toc} that
can be nested.  One can record all timings while a complex script is running,
and examine the values later.  It is also possible to instrument the timing call
with custom callbacks.  In addition, this package provides class 'Stack',
implemented as a vector, and class 'List', implemented as a list, both of whic
support operations 'push', 'pop', 'first', 'last' and 'clear'.")

    (description
     "Performs brace expansions on strings.  Made popular by Unix shells, brace
expansion allows users to concisely generate certain character vectors by taking
a single string and (recursively) expanding the comma-separated lists and
double-period-separated integer and character sequences enclosed within braces
in that string.  The double-period-separated numeric integer expansion also
supports padding the resulting numbers with zeros.")
