.SH DESCRIPTION
+The \fB@IMAGEX_PROGNAME@ capture\fR and \fB@IMAGEX_PROGNAME@ append\fR commands
+create a Windows Imaging (WIM) image from a directory tree. The
+\fB@IMAGEX_PROGNAME@ capture\fR command creates a new WIM file containing the
+captured image, while the \fB@IMAGEX_PROGNAME@ append\fR command appends the
+captured image to an existing WIM file.
.PP
-
-The \fBimagex capture\fR and \fBimagex append\fR commands create a Windows
-Imaging (WIM) image from a directory tree. The \fBimagex capture\fR command
-creates a new WIM file containing the captured image, while the \fBimagex
-append\fR command appends the captured image to an existing WIM file.
-
A WIM image is an independent directory tree in the WIM file. A WIM file may
contain any number of separate images. However, files are stored only one time
in the entire WIM, regardless of how many images the file appears in.
-
+.PP
\fISOURCE\fR specifies the location of the files to create the new WIM image
from. If \fISOURCE\fR is a directory, the WIM image is captured from that
-directory. Alternatively, if \fISOURCE\fR is a regular file or block device, it
-is interpreted as a NTFS volume from which a WIM image is to be captured. Still
-alternatively, if the \fB--source-list\fR option is given, \fISOURCE\fR is
-interpreted as a file that itself provides a list of files and directories to
-include in the new WIM image.
-
-\fIIMAGE_NAME\fR and \fIDESCRIPTION\fR specify the name and description of the
-new image. If \fIIMAGE_NAME\fR is not given, it is taken to be the same as the
-base name of \fISOURCE\fR. If \fIDESCRIPTION\fR is not given, no description is
-given to the new image.
-
-.SH NORMAL MODE
-
-The normal image capture mode is entered when \fISOURCE\fR specifies a
-directory. The WIM image will be captured from the directory tree rooted at
+directory. Alternatively, if the \fB--source-list\fR option is given,
+\fISOURCE\fR is interpreted as a file that itself provides a list of
+files and directories to include in the new WIM image. Still
+alternatively, only on UNIX builds of wimlib, if \fISOURCE\fR is a
+regular file or block device, it is interpreted as an NTFS volume from
+which a WIM image is to be captured.
+.PP
+\fIIMAGE_NAME\fR and \fIIMAGE_DESCRIPTION\fR specify the name and description of
+the new image. If \fIIMAGE_NAME\fR is not given, it is taken to be the same as
+the base name of \fISOURCE\fR. If \fIIMAGE_DESCRIPTION\fR is not given, no
+description is given to the new image.
+.SH NORMAL MODE (UNIX)
+This section documents how files are captured from a directory on UNIX. See
+\fBWINDOWS VERSION\fR for the corresponding documentation for the Windows
+version.
+.PP
+On UNIX, the "normal" image capture mode is entered when \fISOURCE\fR specifies
+a directory. The WIM image will be captured from the directory tree rooted at
this directory. The directory may be on any type of filesystem.
-
-In this normal image capture mode, we capture the following information from the
-directory tree:

+UNIX file owners, groups, and modes. The resulting WIM image will contain no
+security information (file permissions). (Exception: see the \fB--unix-data\fR
option.)
-
.IP \[bu]
-No alternate data streams will be captured, since these do not exist on
-POSIX-compliant filesystems. The resulting WIM image will not contain any
-alternate data streams.
-
-.SH NTFS MODE
-
-A special image capture mode is entered when \fISOURCE\fR is a regular file or
-block device. \fISOURCE\fR is interpreted as an NTFS volume and opened using
-libntfs-3g. If successful, a WIM image is captured containing the contents of
-the NTFS volume, including NTFS-specific data.

+Extended attributes.
+.SH NTFS MODE (UNIX)
+This section documents how files are captured from an NTFS volume image on UNIX.

+.PP
+More specifically, in this mode, the following types of information are captured
from the NTFS volume:
-
.IP \[bu] 4
All data streams of all files, including the un-named data stream as well as all
named data streams.
.IP \[bu]
All names of all files, including names in the Win32 namespace, DOS namespace,
Win32+DOS namespace, and POSIX namespace. This includes hard links.
-
-.SH SOURCE LIST MODE
-
-Yet another capture mode is entered when the \fB--source-list\fR option is
-given. It is essentially an extension of the \fBNORMAL MODE\fR that allows
-multiple files or directories to be incorporated into a WIM image using a single
-\fBimagex capture\fR command. See the documentation for \fB--source-list\fR
-below.
-
+.SH WINDOWS VERSION
+The Windows versions of \fB@IMAGEX_PROGNAME@ capture\fR and \fB@IMAGEX_PROGNAME@
+append\fR act similarly to the corresponding commands of Microsoft's ImageX.
+For best results, the directory being captured 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@ capture\fR and \fB@IMAGEX_PROGNAME@ append\fR
+try to archive 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 and if the version of
+Windows is Vista or later.
+.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 captured.)
+.IP \[bu]
+File and directory creation, access, and modification timestamps to the nearest
+100 nanoseconds.
+.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
+captured if the user does not have permission to read them.
+.IP \[bu]
+File attributes, including hidden, sparse, compressed, encrypted, etc.
+Encrypted files will be stored in encrypted form rather than in plain text.
+.IP \[bu]
+DOS names (8.3) names of files; however, the failure to read them is not
+considered an error condition.
+.IP \[bu]
+Hard links, excluding directory hard links (which aren't supposed to exist
+anyway).

-\fBimage append\fR does not support appending an image to a split WIM.

+\fB@IMAGEX_PROGNAME@ append\fR does not support appending an image to a split WIM.
+.PP
The different capture modes only specify the data that is captured and don't
specify a special WIM format. A WIM file can contain images captured using
different modes. However, all images in a WIM must have the same compression
-type, and \fBimagex\fR always enforces this.
-
-\fBimagex\fR writes WIMs having the version number 0x10d00 and a compressed
+type, and \fB@IMAGEX_PROGNAME@\fR always enforces this.
+.PP
+\fB@IMAGEX_PROGNAME@\fR writes WIMs having the version number 0x10d00 and a compressed
stream chunk size of 32768. The only WIMs I've seen that are different from
this are some pre-Vista WIMs that had a different version number.
-
-Unless \fB--rebuild\fR is specified, aborting an \fBimagex append\fR command
-mid-way through has a small chance of corrupting the WIM file. However, a
-precaution is taken against this, so it should be very unlikely. In the event
-of an aborted \fBimagex append\fR, \fBimagex optimize\fR may be run to remove
-extra data that may have been partially appended to the physical WIM file but
-not yet incorporated into the structure of the WIM.
-
-Capturing or appending an image happens in two main phases: (1) scanning the
-directory or NTFS volume to checksum all the files and determine the streams to
-be written, and (2) writing the new streams to the WIM file. Streams are not
-stored in memory after (1), since there could easily be gigabytes of data;
-instead, they are read again during step (2); however, duplicate streams in the
-image, and streams already existing in any other image in the WIM, are not read
-again. In the future, it may be possible to introduce the ability to capture an
-image with reading each file only one time, although this mode would have some
-limitations--- for example, a stream might be compressed only to be thrown away
-as a duplicate once it's been checksummed.
-
+.PP
+It is safe to abort an \fB@IMAGEX_PROGNAME@ append\fR command partway through;
+however, after doing this, it is recommended to run \fB@IMAGEX_PROGNAME@
+optimize\fR to remove any data that was appended to the physical WIM file but
+not yet incorporated into the structure of the WIM, unless \fB--rebuild\fR was
+specified, in which case you should delete the temporary file left over.
+.PP
\fISOURCE\fR may be a symbolic link to a directory rather than a directory
itself. However, additional symbolic links in subdirectories, or in additional
source directories not destined for the WIM image root (with
\fB--source-list\fR), are not dereferenced unless \fB--dereference\fR is
specified.
-
+.PP
+With the UNIX version of \fB@IMAGEX_PROGNAME@\fR, it is possible to create a WIM
+image containing files with names differing only in case, or files with names
+containing the characters ':', '*', '?', '"', '<', '>', '|', or '\\', which are
+valid on POSIX-compliant filesystems but not Windows. Be warned that such files
+will not be extracted by default by the Windows version of
+\fB@IMAGEX_PROGNAME@\fR, and Microsoft's ImageX might get confused by such
+names.
