-WIM integrity table is supported (\fB--check\fR option to many commands)
-.SH DIFFERENCES FROM MICROSOFT IMAGEX
-Although \fB@IMAGEX_PROGNAME@\fR shares some similarities with Microsoft's
-implementation of ImageX, this section lists some of the many 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]
-\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). It also makes it easy to
-recompress a WIM file at the highest compression level.
-.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
+Support for WIM integrity tables. An integrity table is a list of SHA-1 message
+digests appended to the end of a WIM file which gives checksums over the WIM
+file itself. The \fB--check\fR option to several \fB@IMAGEX_PROGNAME@\fR
+commands can be used to verify or add integrity tables.
+.IP \[bu]
+Support for "pipable" WIMs. This is a wimlib extension and is not compatible
+with the Microsoft implementation. A pipable WIM, created with
+\fB@IMAGEX_PROGNAME@ capture\fR with the \fB--pipable\fR option, can be written
+to standard output or read from standard input. This can be used to pipe images
+to or from a server over the network to implement fast filesystem imaging and
