| <!-- man begin DESCRIPTION elfedit --> |
| <p><samp><span class="command">elfedit</span></samp> updates the ELF header and program property of ELF |
| files which have the matching ELF machine and file types. The options |
| control how and which fields in the ELF header and program property |
| should be updated. |
| |
| <p><var>elffile</var><small class="dots">...</small> are the ELF files to be updated. 32-bit and |
| 64-bit ELF files are supported, as are archives containing ELF files. |
