| 27 | # The actual script is filtered through the mkscript program | |
| 28 | # to convert it to a form suitable for including in a C program | |
| 29 | # as a C string literal. | |

| 32 | # A .xr script is for linking without relocation (-r flag). | |
| 33 | # A .xu script is like .xr, but *do* create constructors (-Ur flag). | |
| 34 | # A .xn script is for linking with -n flag (mix text and data on same page). | |
