+\fB@IMAGEX_PROGNAME@ apply\fR extracts an image, or all images, from the Windows
+Imaging (WIM) file \fIWIMFILE\fR.
+.PP
+This command is designed to extract, or "apply", one or more full WIM images.
+If you instead want to extract only certain files or directories contained in a
+WIM image, consider using \fB@IMAGEX_PROGNAME@ extract\fR or
+\fB@IMAGEX_PROGNAME@ mount\fR instead.
+.PP
+\fIIMAGE\fR specifies the WIM image to extract. It may be a 1-based index of an
+image in the WIM, the name of an image in the WIM, or the keyword "all" to
+indicate that all images are to be extracted. Use the \fB@IMAGEX_PROGNAME@
+info\fR (1) command to show what images a WIM file contains. \fIIMAGE\fR may be
+omitted if \fIWIMFILE\fR contains only one image.
+.PP
+\fITARGET\fR specifies where to extract the WIM image(s) to. If \fITARGET\fR
+specifies a directory, the WIM image(s) are extracted to that directory. If
+\fITARGET\fR specifies a non-existent file, a directory is created in that
+location and the WIM image(s) are extracted to that directory. Alternatively,
+on UNIX only, if \fITARGET\fR specifies a regular file or block device, it is
+interpreted as an NTFS volume to which the WIM image is to be extracted.
+.PP
+\fB@IMAGEX_PROGNAME@ apply\fR supports applying images from stand-alone WIMs as
+well as split WIMs. See \fBSPLIT WIMS\fR.
+.SH NORMAL MODE (UNIX)
+This section documents how files are extracted on UNIX from the WIM image to a
+directory. See \fBWINDOWS VERSION\fR for the corresponding documentation for
+the Windows version.
+.PP
+On UNIX, the "normal" extraction mode is entered when \fITARGET\fR is a
+directory or non-existent file. If a single WIM image is being extracted, it is
+extracted with the root directory of the image corresponding to the directory
+named by \fITARGET\fR; or, if the keyword \fBall\fR is given, the images are
+extracted into subdirectories of \fITARGET\fR that are be named after the image
+names, falling back to the image index for an image with no name. \fITARGET\fR
+can specify a directory on any type of filesystem.
+.PP
+In the "normal" mode of extraction on UNIX, the following information is
+extracted from the WIM image(s):
+.IP \[bu] 4
+The default (unnamed) data stream of each file
+.IP \[bu]
+Hard links
+.IP \[bu]
+File and directory creation, access, and modification timestamps to the nearest
+100 nanoseconds, if supported by the underlying filesystem, operating system,
+and C library
+.IP \[bu]
+Symbolic links and junction points. Drive letters will be stripped.
+(Note: see \fB--rpfix\fR and \fB--norpfix\fR for documentation on how absolute
+symbolic links and junctions are applied.)
+.PP
+However, in the "normal" mode of extraction on UNIX, the following information
+will \fInot\fR be extracted from the WIM image(s):
+.IP \[bu] 4
+Security descriptors (file permissions) except through the extensions available
+through the \fB--unix-data\fR option
+.IP \[bu]
+The alternate (named) data streams for each file
+.IP \[bu]
+Reparse points other than symbolic links and junction points
+.IP \[bu]
+Certain file attributes such as compression, encryption, and sparseness.
+.IP \[bu]
+Short (DOS) names for files
+.SH NTFS MODE (UNIX)
+This section documents how files are extracted directly to an NTFS volume image
+on UNIX. See \fBWINDOWS VERSION\fR for the corresponding documentation for the
+Windows version.
+.PP
+On UNIX, a special extraction mode is entered when \fITARGET\fR is a regular
+file or block device. If this is the case, \fITARGET\fR is interpreted as an
+NTFS volume and opened using libntfs-3g. If successful, the WIM image is
+extracted to the root of the NTFS volume in a special mode that preserves all
+information contained in the WIM image. \fIIMAGE\fR may not be "all" for this
+action.
+.PP
+The NTFS volume does not need to be empty, although it's expected that it be
+empty for the intended use cases. A new NTFS filesystem can be created using
+the \fBmkntfs\fR (8) command.
+.PP
+The NTFS extraction mode is not available if wimlib was compiled using the
+\fB--without-ntfs-3g\fR option.
+.PP
+Please note that the NTFS extraction mode is \fInot\fR entered if \fITARGET\fR
+is a directory, even if an NTFS filesystem is mounted on \fITARGET\fR. You must
+specify the NTFS volume itself (and it must be unmounted, and you must have
+permission to write to it).
+.PP
+In the NTFS extraction mode on UNIX, the following information will be extracted
+from the WIM image:
+.IP \[bu] 4
+The data streams of all files, including the un-named data stream as well as all
+named data streams.
+.IP \[bu]
+Reparse points, including symbolic links, junction points, and other reparse
+points.
+.IP \[bu]
+Hard links.
+.IP \[bu]
+File and directory creation, access, and modification timestamps are set to the
+100-nanosecond resolution values specified in the WIM file.
+.IP \[bu] 4
+The security descriptor for each file is applied if there is one specified in
+the WIM.
+.IP \[bu]
+File attribute flags are applied.
+.IP \[bu]
+Short (DOS) names for files are extracted. The corresponding long name for each
+DOS name is made to be a Win32 name. Any additional names for the file in the
+same directory are made to be names in the POSIX namespace.
+.PP
+However, the extraction of encrypted files is not supported in this mode.
+.PP
+Since all (or almost all) information from the WIM image is restored in this
+mode, it is possible to restore an image of an actual Windows installation using
+\fB@IMAGEX_PROGNAME@\fR on UNIX in addition to with \fB@IMAGEX_PROGNAME@\fR on
+Windows. In the examples at the end of this manual page, there is an example of
+applying an image from the "install.wim" file contained in the installation
+media for Windows Vista, Windows 7, and Windows 8 in the "sources" directory.
+.PP
+But in order to actually boot Windows from an applied image, you must understand
+the boot process of Windows versions Vista and later. Basically, it is the
+following:
+.nr step 1 1
+.IP \n[step]. 3
+The Master Boot Record loads the Volume Boot Record (also called the Boot
+Sector) of the active partition, which is on an NTFS filesystem. This partition
+is called the "system partition".
+.IP \n+[step].
+The "bootmgr" program on the "system partition" is loaded (\\BOOTMGR).
+.IP \n+[step].
+bootmgr loads the Boot Configuration Data (\\Boot\\BCD) from the "system
+partition".
+.IP \n+[step].
+Based on the information contained in the Boot Configuration Data, a loader for
+the Windows kernel is executed from the "Boot" partition, which is where Windows
+is installed.
+.PP
+So let's say you applied an image from an existing "install.wim" as in the
+example, or you've applied a custom Windows image that you've created using the
+\fB@IMAGEX_PROGNAME@ capture\fR (1) command. You've just applied the "Boot" partition, or
+the main Windows partition, but there is no "System" partition yet (i.e. no
+\\BOOTMGR and no \\Boot\\BCD).
+.PP
+A "System" partition can be created created by running the "bcdboot.exe" program
+from within Windows or Windows PE. Alternatively, you can capture a separate
+WIM image containing the "System" partition. Or, the "System" partition may the
+same as the "Boot" partition, so the two "partitions" may be combined in one WIM
+image. However, as the \\Boot\\BCD file contains the Windows bootloader
+configuration, a WIM containing it can only be used on systems where you are
+setting up the same bootloader configuration, including the same partition
+layout.
+.PP
+Besides setting up the files on the "System" partition, don't forget to set the
+bootable flag on it, and have a master boot record that loads the bootable
+partition (Windows' MBR does, and SYSLINUX provides an equivalent MBR).
+.SH WINDOWS VERSION
+The Windows version of \fB@IMAGEX_PROGNAME@ apply\fR acts similarly to the
+corresponding command of Microsoft's ImageX. For best results, the target
+directory should be on an NTFS volume and you should be running with
+Administrator privileges; however, non-NTFS filesystems and running without
+Administrator privileges are also supported.
+.PP
+On Windows, \fB@IMAGEX_PROGNAME@ apply\fR tries to extract as much data as
+possible. This includes:
+.IP \[bu] 4
+All data streams of all files. This includes the default file contents, as well
+as named data streams if supported by the filesystem.
+.IP \[bu]
+Reparse points, including symbolic links, junction points, and other reparse
+points, if supported by the underlying filesystem. (Note: see
+\fB--rpfix\fR and \fB--norpfix\fR for documentation on how absolute symbolic
+links and junctions are applied.)
+.IP \[bu]
+File and directory creation, access, and modification timestamps.
+.IP \[bu]
+Security descriptors, if supported by the filesystem and \fB--no-acls\fR is not
+specified. Furthermore, unless \fB--strict-acls\fR is specified, the security
+descriptor for individual files or directories may be omitted or only partially
+set if the user does not have permission to set them.
+.IP \[bu]
+File attributes, including hidden, sparse, compressed, encrypted, etc, when
+supported by the filesystem.
+.IP \[bu]
+DOS names (8.3) names of files; however, the failure to set them is not
+considered an error condition.
+.IP \[bu]
+Hard links, if supported by the filesystem.
+.PP
+Note: encrypted files will be extracted as raw encrypted data if the filesystem
+does not support encryption. Compressed files and directories (with the
+compression attribute set) will be extracted as uncompressed if the filesystem
+does not support transparent compression.
+.SH SPLIT WIMS
+You may use \fB@IMAGEX_PROGNAME@ apply\fR to apply images from a split WIM. The
+\fIWIMFILE\fR argument is used to specify the first part of the split WIM, and
+the \fB--refs\fR="\fIGLOB\fR" option is used to provide a shell-style file glob
+that specifies the additional parts of the split WIM. \fIGLOB\fR is expected to
+be a single string on the command line, so \fIGLOB\fR must be quoted so that it
+is protected against shell expansion. \fIGLOB\fR must expand to all parts of
+the split WIM, except optionally the first part which may either omitted or
+included in the glob (but the first part MUST be specified as \fIWIMFILE\fR as
+well).
+.PP
+Here's an example. The names for the split WIMs usually go something like:
+.RS
+.PP
+.nf
+mywim.swm
+mywim2.swm
+mywim3.swm
+mywim4.swm
+mywim5.swm
+.RE
+.nf
+.PP
+To apply the first image of this split WIM to the directory "dir", run:
+.PP
+.RS
+@IMAGEX_PROGNAME@ apply mywim.swm 1 dir --ref="mywim*.swm"
+.RE
