.SH DESCRIPTION
-\fBimagex\fR is able to deal with archives in the Windows Imaging Format (.wim
-files). Its interface is meant to be similar to Microsoft's imagex.exe program.
-
-To do its work, \fBimagex\fR uses \fBwimlib\fR, a library which provides
-interfaces for manipulating WIM archives. You could wimlib in your own programs
-if you wanted to. Wimlib's public interface is documented.
-
-See \fBWARNING\fR.
-
+\fB@IMAGEX_PROGNAME@\fR deals with archives in the Windows Imaging Format (.wim
+files). Its interface is meant to be similar to Microsoft's "imagex.exe"
+program, but it also provide many useful extensions.
+.PP
+To do its work, \fB@IMAGEX_PROGNAME@\fR uses \fBwimlib\fR, a C library which
+provides interfaces for manipulating WIM archives. You can wimlib in your own
+programs if desired, although \fB@IMAGEX_PROGNAME@\fR already provides access to
+most of wimlib's functionality. In some cases, however, there are general
+interfaces which are only used by \fB@IMAGEX_PROGNAME@\fR in a specific way, so
+it may be worth taking a look if you're looking to do something beyond what
+\fB@IMAGEX_PROGNAME@\fR directly supports.
.SH COMMANDS
-
-There is a separate manual page for each \fBimagex\fR command.
-
+\fB@IMAGEX_PROGNAME@\fR accepts one of a number of commands (listed above in
+\fBSYNOPSYS\fR), and additional arguments depending on the specific command.
+Although \fB@IMAGEX_PROGNAME@\fR will print usage information with \fB--help\fR
+or if you invoke it incorrectly, the full documentation for each
+\fB@IMAGEX_PROGNAME@\fR command can be found in the appropriate manual page.
+.PP
+Note: to save typing, if appropriate hard links or batch files have been
+installed, a command \fB@IMAGEX_PROGNAME@ \fICOMMAND\fR can also be accessed as
+simply \fBwim\fICOMMAND\fR; for example, \fBwimapply\fR for \fB@IMAGEX_PROGNAME@
+apply\fR.

-
-.SH UNSUPPORTED FEATURES
-The following features are currently unsupported:
-.IP \[bu] 2
-File permissions and security descriptors are ignored. The information
-contained in them in an existing WIM will be lost when wimlib writes a WIM file.
-This does not seem to matter for Windows PE, but this means that you should not
-use this program to image a drive containing Windows Vista/7/8 and expect it to
-be applied with the correct file permissions.
-.IP \[bu] 2
-Split WIMs are not fully supported. These can be used to split up a WIM to fit
-on multiple CDs, if you can't use a DVD for some reason. You can use
-\fBimagex join\fR to combine split WIMs, but you cannot yet create split WIMs.
-.IP \[bu] 2
-The \fB--verify\fR option, for all commands that use it. Without this option,
-there theoretically could be a SHA1 hash collision between two files, although
-it's very unlikely.
-.IP \[bu] 2
-The \fB--config\fR option, for all commands that use it.
-.IP \[bu] 2
-Alternate stream entries
-.IP \[bu] 2
-Different versions of the WIM file format (if different versions even exist)
-
-Also see the Doxygen documentation for Wimlib.

.SH DIFFERENCES FROM MICROSOFT IMAGEX
-
-See \fBUNSUPPORTED FEATURES\fR.
-
-The \fB/scroll\fR and \fB/log\fR switches from Microsoft's version imagex are
-not planned to be implemented. Note that to scroll the output in the UNIX shell
-you can just pipe the output into \fBless\fR(1).
-
-Some features, such as the ability to keep files hard-linked when they are
-extracted from a WIM, are not available in Microsoft's version of imagex.
-
-See the documentation for each command; in some cases they do not do exactly the
-same thing as imagex.exe.
-
-Obviously, this version of imagex is free software but Microsoft's version is
-not.
-
-.SH WARNING
-
-Note: \fBwimlib\fR and \fBimagex\fR are experimental. Use Microsoft's
-imagex.exe if you have to make sure your WIM files are made correctly. Not all
-features listed under \fBSUPPORTED FEATURES\fR have been thoroughly tested.
-Feel free to submit a bug report if you find a bug.
-
-Some parts of the WIM file format are poorly documented or even completely
-undocumented, so these parts had to be reverse engineered for compatibility
-purposes.
-
+Although \fB@IMAGEX_PROGNAME@\fR shares some similarities with Microsoft's
+implementation of ImageX, this section lists some noteworthy differences between
+the two programs:
+.IP \[bu] 4
+\fB@IMAGEX_PROGNAME@\fR is supported on both UNIX-like systems and Windows;
+thus, some functionality was designed around this.
+.IP \[bu]
+The command-line syntax of the two programs is similar but not exactly the same.
+.IP \[bu]
+Because Microsoft designed the WIM file format to accomodate Windows-specific
+and NTFS-specific features, on UNIX-like systems wimlib must have two separate
+image capture and application modes (although the \fB@IMAGEX_PROGNAME@\fR
+commands for the modes are the same): one for image capture and application
+from/to a directory, and one for the capture or application of an image
+specifically from/to an NTFS volume.
+.IP ""
+Note: the above applies to builds of \fB@IMAGEX_PROGNAME@\fR for UNIX-like
+systems. On the Windows build, there is only one image capture and application
+mode, similar to Microsoft's ImageX.
+.IP \[bu]
+wimlib supports multithreaded compression, which can make it much faster to
+create compressed WIM files.
+.IP \[bu]
+wimlib's XPRESS compressor is slightly better than Microsoft's (in terms of
+compression ratio).
+.IP \[bu]
+wimlib's LZX compressor is slightly worse than Microsoft's (in terms of
+compression ratio), but it's still better than XPRESS compression.
+.IP \[bu]
+\fB@IMAGEX_PROGNAME@ capture\fR defaults to LZX ("maximum") compression for new
+WIMs, as opposed to Microsoft's software which defaults to XPRESS ("fast")
+compression.
+.IP \[bu]
+\fB@IMAGEX_PROGNAME@\fR offers the extra commands \fB@IMAGEX_PROGNAME@
+extract\fR and \fB@IMAGEX_PROGNAME@ update\fR, which let you quickly extract
+files from or make changes to a WIM image without mounting it.
+.IP \[bu]
+\fB@IMAGEX_PROGNAME@\fR offers the extra command \fB@IMAGEX_PROGNAME@
+optimize\fR, which lets you easily remove wasted space in a WIM (which can arise
+after a WIM image is appended or mounted read-write).
+.IP \[bu]
+\fB@IMAGEX_PROGNAME@\fR also offers the command \fB@IMAGEX_PROGNAME@ join\fR,
+which lets you easily join the parts of a split WIM.
+.IP \[bu]
+For convenience, \fB@IMAGEX_PROGNAME@\fR automatically preserves the integrity
+table in WIMs that have one, even when \fB--check\fR is not specified.
+.IP \[bu]
+wimlib supports a special "pipable" WIM format (not compatible with Microsoft's
+software). This allows capturing and applying images directly to standard
+output or from standard input, respectively; this can be used to pipe images to
+or from a server over the network to implement fast filesystem imaging and
+restore.
+.IP \[bu]
+\fB@IMAGEX_PROGNAME@ capture\fR and \fB@IMAGEX_PROGNAME@ append\fR support
+options to optimize incremental backups and to create "delta" WIM files.
+.IP \[bu]
+wimlib (and \fB@IMAGEX_PROGNAME@\fR via \fB@IMAGEX_PROGNAME@ capture\fR)
+supports combining multiple separate directories and files together in a
+configurable way to create a WIM image.
+.IP \[bu]
+Microsoft's ImageX has some weird limitations, like it won't let you extract a
+WIM on a shared folder, and it requires some commands to be run only from
+Windows PE and not from regular Windows. \fB@IMAGEX_PROGNAME@\fR does not have
+these unusual limitations.
+.IP \[bu]
+There are bugs in Microsoft's WIM library and I obviously have not included the
+same bugs in wimlib, although in some cases I have had to work around bugs for
+compatibility purposes.
+.IP \[bu]
+wimlib (and \fB@IMAGEX_PROGNAME@\fR via \fB@IMAGEX_PROGNAME@ mount\fR) support
+mounting an image from a split WIM, but Microsoft's software does not. (Note:
+this functionality is not available in Windows builds of wimlib and
+\fB@IMAGEX_PROGNAME@\fR.)
+.IP \[bu]
+\fB@IMAGEX_PROGNAME@ capture\fR supports a special mode where UNIX file modes,
+owners, and groups are stored. (Note: this functionality is only available in
+builds of wimlib for UNIX-like systems.)
+.SH LOCALES AND CHARACTER ENCODINGS
+On Windows, wimlib works in UTF-16LE, and there should be no problems with
+character encodings.
+.PP
+On UNIX, wimlib works primarily in the locale-dependent multibyte encoding,
+which you are strongly recommended to set to UTF-8 to avoid any problems.
+.SH CASE SENSITIVITY
+The case sensitivity of \fB@IMAGEX_PROGNAME@\fR differs somewhat between
+UNIX-like systems and Windows. Filenames are internally treated as
+case-sensitive, but on Windows paths actually provided by the user will be
+treated as case-insensitive in order to get the "expected" behavior. Otherwise,
+options and non-path arguments should be specified in lower case.
+.SH LICENSE
+wimlib and \fB@IMAGEX_PROGNAME@\fR are distributed under the GNU General Public
+License version 3 or later. Be aware this means this software is provided as-is
+and has no warranty; see COPYING for details.
