+ * This is the documentation for the library interface of wimlib 1.6.2, 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
*
* @brief Extract files, directories, and images from a WIM.
*
- * wimlib_extract_image() extracts, or "applies", an image from a WIM
- * (represented, as usual, by a ::WIMStruct). This normally extracts the image
- * to a directory, but when supported by the build of the library there is also
- * a special NTFS volume extraction mode (entered when
- * ::WIMLIB_EXTRACT_FLAG_NTFS is specified) that allows extracting a WIM image
- * directly to an unmounted NTFS volume. Various other flags allow further
- * customization of image extraction.

+ * is specified) that allows extracting a WIM image directly to an unmounted
+ * NTFS volume. Various other flags allow further customization of image
+ * extraction.
*
- * Another function, wimlib_extract_files(), is also provided. It can extract
- * certain files or directories from a WIM image, instead of a full image.
+ * wimlib_extract_paths() and wimlib_extract_pathlist() allow extracting a list
+ * of (possibly wildcard) paths from a WIM 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_image_from_pipe() extracts an image 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
- * <b>wimlib-imagex extract</b>.

+ * with wimlib_extract_image() or wimlib_extract_paths(). This is done by
* calling wimlib_reference_resource_files() or wimlib_reference_resources().
