 .Sh DESCRIPTION
 These functions set the format that will be used for the archive.
 .Pp
-The library can write
+The library can write a variety of common archive formats.
-POSIX octet-oriented cpio format archives,
+
-POSIX-standard
-.Dq pax interchange
-format archives,
-traditional
-.Dq shar
-archives,
-enhanced
-.Dq dump
-shar archives that store a variety of file attributes and handle binary files,
-and
-POSIX-standard
-.Dq ustar
-archives.
-The pax interchange format is a backwards-compatible tar format that
-adds key/value attributes to each entry and supports arbitrary
-filenames, linknames, uids, sizes, etc.
-.Dq Restricted pax interchange format
-is the library default; this is the same as pax format, but suppresses
-the pax extended header for most normal files.
-In most cases, this will result in ordinary ustar archives.

+.It Fn archive_write_set_format
+Sets the format based on the format code (see

+for the full list of format codes).
+In particular, this can be used in conjunction with
+.Fn archive_format
+to create a new archive with the same format as an existing archive.
+.It Fn archive_write_set_format_by_name
+Sets the corresponding format based on the common name.
