19 /* OPTP_CHAIN is the normal behavior, i.e. single-letter options can be |
|
20 * "chained" together: 'lr -lR'. Use for normal command line programs. |
|
21 * OPTP_MIDLONG allows '-display foo' -like args but disables chaining |
|
22 * of single-letter options. X programs should probably use this. |
|
23 * OPTP_IMMEDIATE allows immediate arguments (-I/usr/include) (and disables |
|
24 * chaining and midlong options). |
|
25 * OPTP_NO_DASH is the same as OPTP_CHAIN but allows the dash to be omitted |
|
26 * for 'tar xzf foo' -like behavior. |
|
27 * Long '--foo=bar' options are supported in all of the modes. |
