+.SH NAME
+\f4binarsys\f1 \- remote system information for the \f4ckbinarsys\f1 command
+.SH DESCRIPTION
+\f4binarsys\f1
+contains lines of the form:
+.sp .5
+.ce
+\f2remote_system_name\f4:\f2val\f1
+.sp .5
+where \f2val\f1 is either \f4Y\f1 or \f4N\f1.
+This line indicates whether that particular remote system can properly
+deal with messages having binary content.
+The absence of an entry for a particular system 
+or absence of the \f4binarsys\f1 file altogether will imply \f4N\f1o.
+.PP
+Blank lines or lines beginning with \f4#\f1 are considered
+comments and ignored.
+Should a line of \f4Default=y\f1 be encountered,
+the default condition for missing entries described in the previous paragraph
+is reversed to be \f4Y\f1es.
+Another line of \f4Default=n\f1 will restore the default condition to \f4N\f1o.
+.PP
+\f4mail\f1 is distributed with the \f4binarsys\f1
+file containing only a \f4Default=y\f1 line.
