8  * The intention is to include near-verbatim copies of the EFI headers
9  * required by iPXE. This is achieved using the import.pl script in
10  * this directory. Run the import script to update the local copies
11  * of the headers:
12  *
13  * ./import.pl /path/to/edk2/edk2
14  *
15  * where /path/to/edk2/edk2 is the path to your local checkout of the
16  * EFI Development Kit.
17  *
18  * Note that import.pl will modify any #include lines in each imported
19  * header to reflect its new location within the iPXE tree. It will
20  * also tidy up the file by removing carriage return characters and
21  * trailing whitespace.
