+ * RMAIL -- UUCP mail server.
+ *
+ * This program reads the >From ... remote from ... lines that UUCP is so
+ * fond of and turns them into something reasonable. It then execs sendmail
+ * with various options built from these lines.
+ *
+ * The expected syntax is:
+ *
+ * <user> := [-a-z0-9]+
+ * <date> := ctime format
+ * <site> := [-a-z0-9!]+
+ * <blank line> := "^\n$"
+ * <from> := "From" <space> <user> <space> <date>
+ * [<space> "remote from" <space> <site>]
+ * <forward> := ">" <from>
+ * msg := <from> <forward>* <blank-line> <body>
+ *
+ * The output of rmail(8) compresses the <forward> lines into a single
+ * from path.
+ *
+ * The err(3) routine is included here deliberately to make this code
+ * a bit more portable.
