| 440 | %% Describe some kind of program object. The CAT names the category of thing |
| 441 | %% being described -- this will be shown in the header, and index. The |
| 442 | %% SYNOPSIS is an implicit `prog' environment in which invoking the thing can |
| 443 | %% be summarized. |
| 444 | %% |
| 445 | %% The {...}... are any additional arguments required by the category's kind |
| 446 | %% (e.g., method specializers). |
| 447 | %% |
| 448 | %% The NAME is the name of the thing, which ends up in the index and |
| 449 | %% cross-reference label. If omitted, it defaults to the first word of the |
| 450 | %% SYNOPSIS, except that there are some special cases. |
| 451 | %% |
| 452 | %% The MOD is the modifier to apply. If omitted, it will usually default to |
| 453 | %% `plain', but in the absence of a NAME, some kinds of synopses are |
| 454 | %% recognized specially: |
| 455 | %% |
| 456 | %% * `setf (NAME ...) ...': selects NAME, and defaults MOD to `setf'. |
| 457 | %% |
| 458 | %% * `*NAME*': selects NAME, without the earmuffs, and defaults MOD to |
| 459 | %% `muffs'. |
| 460 | %% |
| 461 | %% * `:NAME': selects NAME, withtout the colon, and defaults MOD to `kwd'. |

| 491 | %% * `muffs': the LABEL should be `*NAME*', i.e., with the earmuffs |
| 492 | %% restored. |
| 493 | %% * `kwd: the LABEL should be `:NAME', i.e., with the colon restored. |
