.SH VERSION
This man page documents version 1.2 of \fBlibtar\fP.
.SH DESCRIPTION
The \fBth_set_*\fP() functions each set an individual field of the
current tar header associated with the \fITAR\fP handle \fIt\fP.  The
\fBth_set_user\fP() and \fBth_set_group\fP() functions set both the
numeric user/group ID fields and the user/group name text fields.
The other functions set only the field that they refer to.

The \fBth_set_from_stat\fP() function uses the other \fBth_set_*\fP()
functions to set all of the fields at once, based on the data passed to
it in the argument \fIs\fP.

The \fBth_finish\fP() function sets the appropriate constants for the
magic and version fields.  It then calculates the header checksum and
fills in the checksum field.
