.SH NAME
\fBrpm-payloadflags\fR - RPM payload flags
.PP
.SH SYNOPSIS
\fBw\fR[\fIFLAGS\fR].\&\fITYPE\fR
.PP
.SH DESCRIPTION
The payload flags determine how the payload of an RPM package is compressed
when the package is built.\& The flags are stored in the \fBPayloadcompressor\fR
and \fBPayloadflags\fR tags of the package header, which are used to determine
how to uncompress the payload contents during installation.\&
.PP
The peculiar syntax is directly inherited from librpm'\&s \fBFopen()\fR IO API,
where \fBw\fR means opening a file for writing.\&
.PP
The following compression types are supported, but availability may
vary depending on how RPM was compiled.\&

If a flag is omitted, the compressor'\&s default value will be used.\&
.PP
A higher compression level generally means better compression ratio at the
cost of increased resource use and compression times.\&
.PP
\fBT\fR is equivalent to \fBT0\fR and causes the number of threads to be
automatically detected.\& Note that while using threads can speed up compression
considerably, it typically causes the compression ratio to go down, and
make the output less predictable.\&
