| 102 | Install the oils-for-unix binary, and symlinks to it, like osh.

|
| 104 | Usage:
|
| 105 |
|
| 106 | ./install # install the stripped binary
|
| 107 | ./install _bin/cxx-opt-sh/oils-for-unix # or a given binary

|
| 112 | The DESTDIR var allows staged installs. This means that the installed files
|
| 113 | are placed in a temp dir first, NOT the dir they are run from on the target
|
| 114 | machine.
