+ * This is the documentation for the library interface of wimlib 1.5.0, 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
* After creating or modifying a WIM file, you can write it to a file using
* wimlib_write(). Alternatively, if the WIM was originally read from a file
* (using wimlib_open_wim() rather than wimlib_create_new_wim()), you can use
- * wimlib_overwrite() to overwrite the original file.
+ * wimlib_overwrite() to overwrite the original file. Still alternatively, you
+ * can write a WIM directly to a file descriptor by calling wimlib_write_to_fd()
+ * instead.
+ *
+ * wimlib supports a special "pipable" WIM format (which unfortunately is @b not
+ * compatible with Microsoft's software). To create a pipable WIM, call
+ * wimlib_write(), wimlib_write_to_fd(), or wimlib_overwrite() with
+ * ::WIMLIB_WRITE_FLAG_PIPABLE specified. Pipable WIMs are pipable in both
+ * directions, so wimlib_write_to_fd() can be used to write a pipable WIM to a
+ * pipe, and wimlib_extract_image_from_pipe() can be used to apply an image from
+ * a pipable WIM.
*
* Please note: merely by calling wimlib_add_image() or many of the other
* functions in this library that operate on ::WIMStruct's, you are @b not
