Here's the abstract:

When an exceptional situation is encountered by a program, it may
create a condition object describing the situation and then signal the
condition and pass control to a condition handler. The signaler and
handler are two different parts of a system, between which there is a
barrier of abstraction. In order to recover gracefully and flexibly
from exceptional situations, however, the signaler can provide
multiple ways by which the handler can restart the computation, some
of which may require extra input. Often, the decision of which method
of recovery to choose is left up to a human user, who may be prompted
for the input needed to recover. This SRFI proposes a simple mechanism
called restarters to encapsulate the information necessary to restart
a computation with associated interactive prompters.
