Usage: $progname [OPTIONS] |
||||
|
||||
Replace the multilib-unclean header file with multilib-clean stub, while the |
||||
original file is moved to unique architecture-specific location. This should be |
||||
absolutely safe operation (effects of '#include <HEADER.h>' are unchanged. |
||||
|
||||
To allow us to do incompatible changes in this script, packagers should use this |
||||
script only through %ml_fix_c_header wrapping macro. |
||||
|
||||
--destdir absolute path name where the old header file is stored, e.g. |
||||
/some/pat |
||||
--basename when you deal with '/some/path/test.h', specify 'test' |
||||
--buildroot prefix (directory where we play with installed files, usually |
||||
after 'make install DESTDIR=buildroot') |
||||
--additional-suffix we usually move 'test.h' to 'test_\$ARCH.h'. However |
||||
this file could already exit. With this option the multilib |
||||
file will be named 'test_\$ARCH\$SUFFIX.h' |
||||
