boolean chmod(string filename, integer mode)
The chmod function sets the UNIX permissions for the given file based on the mode
supplied. The mode is interpreted like the UNIX shell command, except that it is not
converted to octal. Unless prefixed with a 0, mode is treated as a decimal number.
Under UNIX, three octal numbers specify access privileges for owner, group, and others,
respectively. The modes may be added in order to combine privileges. For example, to
make a file readable and executable, use mode 5. Refer to Table 8.3. You also may wish
to refer to the man page for chmod on your UNIX system.
Under Windows, chmod has limited use. The modes described in Table 8.4 are defined by
Microsoft. They may be combined with the bitwise-or (|), but in practice only write
permission has any meaning. All files in Windows are readable and the file extension
determines whether the file will execute.

This function is part of a group of three functions that change similar information about
files. The other two are chgrp and chown. The fileperms function will tell you the file's
current modes.
