DESCRIPTION
     These functions create and manipulate data objects that represent entries
     within an archive.  You can think of a struct archive_entry as a heavy-
     duty version of struct stat: it includes everything from struct stat plus
     associated pathname, textual group and user names, etc.  These objects
     are used by libarchive(3) to represent the metadata associated with a
     particular entry in an archive.

   Create and Destroy
     There are functions to allocate, destroy, clear, and copy archive_entry
     objects:
     archive_entry_clear()
             Erases the object, resetting all internal fields to the same
             state as a newly-created object.  This is provided to allow you
             to quickly recycle objects without thrashing the heap.
     archive_entry_clone()
             A deep copy operation; all text fields are duplicated.
     archive_entry_free()
             Releases the struct archive_entry object.
     archive_entry_new()
             Allocate and return a blank struct archive_entry object.

   Set and Get Functions
     Most of the functions here set or read entries in an object.  Such func-
     tions have one of the following forms:
     archive_entry_set_XXXX()
             Stores the provided data in the object.  In particular, for
             strings, the pointer is stored, not the referenced string.
     archive_entry_copy_XXXX()
             As above, except that the referenced data is copied into the
             object.
     archive_entry_XXXX()
             Returns the specified data.  In the case of strings, a const-
             qualified pointer to the string is returned.
     String data can be set or accessed as wide character strings or normal
     char strings.  The functions that use wide character strings are suffixed
     with _w.  Note that these are different representations of the same data:
     For example, if you store a narrow string and read the corresponding wide
     string, the object will transparently convert formats using the current
     locale.  Similarly, if you store a wide string and then store a narrow
     string for the same data, the previously-set wide string will be dis-
     carded in favor of the new data.

     There are a few set/get functions that merit additional description:
     archive_entry_set_link()
             This function sets the symlink field if it is already set.  Oth-
             erwise, it sets the hardlink field.

   File Flags
     File flags are transparently converted between a bitmap representation
     and a textual format.  For example, if you set the bitmap and ask for
     text, the library will build a canonical text format.  However, if you
     set a text format and request a text format, you will get back the same
     text, even if it is ill-formed.  If you need to canonicalize a textual
     flags string, you should first set the text form, then request the bitmap
     form, then use that to set the bitmap form.  Setting the bitmap format
     will clear the internal text representation and force it to be recon-
     structed when you next request the text form.

     The bitmap format consists of two integers, one containing bits that
     should be set, the other specifying bits that should be cleared.  Bits
     not mentioned in either bitmap will be ignored.  Usually, the bitmap of
     bits to be cleared will be set to zero.  In unusual circumstances, you
     can force a fully-specified set of file flags by setting the bitmap of
     flags to clear to the complement of the bitmap of flags to set.  (This
     differs from fflagstostr(3), which only includes names for set bits.)
     Converting a bitmap to a textual string is a platform-specific operation;
     bits that are not meaningful on the current platform will be ignored.

     The canonical text format is a comma-separated list of flag names.  The
     archive_entry_copy_fflags_text_w() function parses the provided text and
     sets the internal bitmap values.  This is a platform-specific operation;
     names that are not meaningful on the current platform will be ignored.
     The function returns a pointer to the start of the first name that was
     not recognized, or NULL if every name was recognized.  Note that every
     name--including names that follow an unrecognized name--will be evalu-
     ated, and the bitmaps will be set to reflect every name that is recog-
     nized.  (In particular, this differs from strtofflags(3), which stops
     parsing at the first unrecognized name.)

   ACL Handling
     XXX This needs serious help.  XXX

     An ``Access Control List'' (ACL) is a list of permissions that grant
     access to particular users or groups beyond what would normally be pro-
     vided by standard POSIX mode bits.  The ACL handling here addresses some
     deficiencies in the POSIX.1e draft 17 ACL specification.  In particular,
     POSIX.1e draft 17 specifies several different formats, but none of those
     formats include both textual user/group names and numeric UIDs/GIDs.

     XXX explain ACL stuff XXX
