+ * This is the documentation for the library interface of wimlib 1.6.0, a C
* library for creating, modifying, extracting, and mounting files in the
* Windows Imaging Format. This documentation is intended for developers only.
* If you have installed wimlib and want to know how to use the @b wimlib-imagex
* documented in the man page for @b wimlib-imagex.
*
* - The old WIM format from Vista pre-releases is not supported.
- * - Compressed resource chunk sizes other than 32768 are not supported. This
- * doesn't seem to be a real problem because the chunk size always seems to be
- * this value.
* - wimlib does not provide a clone of the @b PEImg tool, or the @b Dism
* functionality other than that already present in @b ImageX, that allows you
* to make certain Windows-specific modifications to a Windows PE image, such
* Another function, wimlib_extract_files(), is also provided. It can extract
* certain files or directories from a WIM image, instead of a full image.
*
- * A third function, wimlib_extract_image_from_pipe(), allows an image to be
- * extracted from a pipable WIM sent over a pipe; see @ref subsec_pipable_wims.
+ * wimlib_extract_paths() and wimlib_extract_pathlist() allow extracting a set
+ * of paths from a WIM image in a manner that may be easier to use than
+ * wimlib_extract_files(), and also allow wildcard patterns.
+ *
+ * wimlib_extract_image_from_pipe() allows an image to be extracted from a
+ * pipable WIM sent over a pipe; see @ref subsec_pipable_wims.
*
* Note that some details of how image extraction/application works are
* documented more fully in the manual pages for <b>wimlib-imagex apply</b> and
* specialized function (wimlib_split()) is needed to create a split WIM.
