.SH DESCRIPTION
-The \fBwimlib-imagex capture\fR and \fBwimlib-imagex append\fR commands
-create a Windows Imaging (WIM) image from a directory tree. The
-\fBwimlib-imagex capture\fR command creates a new WIM file containing the
-captured image, while the \fBwimlib-imagex append\fR command appends the
-captured image to an existing WIM file.
-These commands are also available as simply \fBwimcapture\fR and \fBwimappend\fR
-if the appropriate hard links or batch files are installed.
+The \fBwimlib-imagex capture\fR and \fBwimlib-imagex append\fR commands create a
+Windows Imaging (WIM) image from a directory tree. If \fIWIMFILE\fR does not
+yet exist, then the two commands are equivalent, and both create a new WIM
+archive and save the image to it. Otherwise, \fBwimlib-imagex capture\fR will,
+with confirmation, overwrite the existing WIM archive with a new one; whereas
+\fBwimlib-imagex append\fR will append the new WIM image to the existing WIM
+archive. These commands are also available as simply \fBwimcapture\fR and
+\fBwimappend\fR if the appropriate hard links or batch files are installed.
.PP
Background information: A WIM image is an independent directory tree in a WIM
-file. A WIM file may contain any number of separate images. WIM files are
-single-instancing with regards to file data, so a file is stored only one time
-in the entire WIM, regardless of how many images the file appears in.
+archive (or "WIM file") A WIM archive may contain any number of separate
+images. WIM archives are single-instancing with regards to file data, so a
+file's data is stored only one time in the entire archive, 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
\fIIMAGE_DESCRIPTION\fR is not specified, no description is given to the new
image.

-As a special case, if \fIWIMFILE\fR is "-", the \fB--pipable\fR option is
-assumed and the WIM file is written to standard output in a special pipable
-format. See the documentation for \fB--pipable\fR for more details.

.SH DIRECTORY CAPTURE (UNIX)
This section documents how \fBwimlib-imagex\fR captures files from a
directory tree on UNIX-like systems. See \fBDIRECTORY CAPTURE (WINDOWS)\fR for
(UNIX)\fR mode from Linux.
.SH OPTIONS
.TP 6
+\fB--force\fR
+With \fBwimlib-imagex capture\fR, always overwrite the existing WIM archive; do
+not prompt.
+.TP
\fB--boot\fR
Specifies that the new image is to be made the bootable image of the WIM archive.
.TP
\fB--check\fR
-For \fBwimlib-imagex append\fR, before performing the append operation,
-check the integrity of \fIWIMFILE\fR if an integrity table is present.
-Furthermore, include an integrity table in the new WIM file
-(\fBwimlib-imagex capture\fR) or the modified WIM file (\fBwimlib-imagex
-append\fR). If this option is not specified, no integrity table is included in
-a WIM file created with \fBwimlib-imagex capture\fR, while a WIM file
-updated with \fBwimlib-imagex append\fR will be written with an integrity
-table if and only if one was present before.
+For \fBwimlib-imagex append\fR, before performing the append operation, check
+the integrity of \fIWIMFILE\fR if an integrity table is present. Furthermore,
+include an integrity table in the new or modified WIM archive. If this option
+is not specified, then an integrity table will be included only when appending
+to an archive that already had an integrity table.
.TP
\fB--compress\fR=\fITYPE\fR[:\fILEVEL\fR]
Specifies the compression format for the new WIM file. \fITYPE\fR may be
relative to the root of the directory tree being captured. When disabled
(\fB--norpfix\fR), absolute symbolic links will be captured exactly as is.
