# shared with many OS's install programs.

In the first form, install SRCFILE to DSTFILE, removing SRCFILE by default.

In the second, create the directory path DIR.

Options:

-b=TRANSFORMBASENAME

-c copy source (using $cpprog) instead of moving (using $mvprog).

-d create directories instead of installing files.

-g GROUP $chgrp installed files to GROUP.

-m MODE $chmod installed files to MODE.

-o USER $chown installed files to USER.

-s strip installed files (using $stripprog).
