<modulesummary>Unix 'tar' utility for reading and writing tar archives</modulesummary>
<description>
<p>The <c>erl_tar</c> module archives and extract files to and from
- a tar file. The tar file format is the POSIX extended tar file format
- specified in IEEE Std 1003.1 and ISO/IEC&nbsp;9945-1. That is the same
- format as used by <c>tar</c> program on Solaris, but is not the same
- as used by the GNU tar program.</p>
+ a tar file. <c>erl_tar</c> supports the <c>ustar</c> format
+ (IEEE Std 1003.1 and ISO/IEC&nbsp;9945-1). All modern <c>tar</c>
+ programs (including GNU tar) can read this format. To ensure that
+ that GNU tar produces a tar file that <c>erl_tar</c> can read,
+ give the <c>--format=ustar</c> option to GNU tar.</p>
<p>By convention, the name of a tar file should end in "<c>.tar</c>".
To abide to the convention, you'll need to add "<c>.tar</c>" yourself
to the name.</p>
