100    When \fBpcretest\fP is built, a configuration option can specify that it should
101    be linked with the \fBlibreadline\fP library. When this is done, if the input
102    is from a terminal, it is read using the \fBreadline()\fP function. This
103    provides line-editing and history facilities. The output from the \fB-help\fP
104    option states whether or not \fBreadline()\fP will be used.

227    The \fB/B\fP modifier is a debugging feature. It requests that \fBpcretest\fP
