-wimlib supports multithreaded compression, which can make it much faster to
-create compressed WIM files.

-.IP \[bu]
-wimlib's \fBimagex capture\fR supports a special mode where UNIX file modes,
-owners, and groups are stored. (Note: this functionality is only available on
-UNIX builds.)
-
-.IP \[bu]
-wimlib's \fBimagex mount\fR and \fBimagex mountrw\fR are much faster than
-Microsoft's versions for some reason. I don't know what they have their program
-do that takes so long to simply set up a mountpoint. (Note: this functionality
-is only available on UNIX builds.)

-wimlib's \fBimagex mount\fR supports mounting an image from a split WIM, but
-Microsoft's software does not. (Note: this functionality is only available on
-UNIX builds.)

-.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". 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 I've just had to do the best I can to read and write WIMs in a
-way that appears to be compatible with Microsoft's software.

+\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.)
+.SH LOCALES AND CHARACTER ENCODINGS
+WIM files themselves store file and stream names using UTF-16LE. On Windows,
+wimlib works in UTF-16LE, so conversions are usually not necessary and there
+should be no problems with character encodings.
+.PP
+On UNIX-like systems, wimlib works primarily in the locale-dependent multibyte
+encoding, which you are strongly recommended to set to UTF-8 to avoid any
+problems. You can alternatively set the environmental variable
+\fBWIMLIB_IMAGEX_USE_UTF8\fR to force \fB@IMAGEX_PROGNAME@\fR to use UTF-8
+character encoding internally, even if the current locale is not UTF-8
+compatible.
+.SH CASE SENSITIVITY
+By default, the case sensitivity of \fB@IMAGEX_PROGNAME@\fR differs somewhat
+between UNIX-like systems and Windows. WIM images may (but usually do not) have
+multiple files with the same case-insensitive name. Internally, wimlib
+stores filenames as case-sensitive, but on Windows paths
+actually provided by the user for use in a WIM image (e.g. for extracting,
+adding, renaming, or deleting files) will by default be treated as
+case-insensitive in order to get the "expected" behavior. This differs from the
+default behavior on UNIX-like systems, where such paths will be treated as
+case-sensitive. Note that with case insensitivity, a path component may in
+general be ambiguous due to multiple files or directories having the same
+case-insensitive name. In such cases, if there is a file or directory with an
+exactly matching name, it is chosen; otherwise, one of the case-insensitively
+matching file or directories is chosen arbitrarily.
+.PP
+The default behavior can be overridden by explicitly setting the environmental
+variable \fBWIMLIB_IMAGEX_IGNORE_CASE\fR to 1, in which case such paths will be
+treated case insensitively, or 0, in which such paths will be treated case
+sensitively.
+.PP
+Regardless of these settings, options and non-path arguments must be specified
+in lower case.
