.SH SYNOPSIS
.B gpgparticipants-prefill
[\fIOPTIONS\fP] \fIEMPTYLIST\fP \fIFILLEDLIST\fP
.SH DESCRIPTION
.B gpgparticipants-prefill
takes a file produced by \fBgpgparticipants\fP (\fIEMPTYLIST\fP) and tries to fill in some
digits into the SHA256 field such that the resulting list actually has a SHA256
checksum that starts with those digits.  In other words, it tries to produce a
file that hashes to a checksum that is partially written down in the file.
Whenever a match is found, a file with the digits filled in is written to
\fIFILLEDLIST\fP\fB.\fP\fIDIGITS\fP.
