Correspondence between DTL and DVI files.

DTL variety sequences-6, version 0.6.0

|
Note: `DTL' stands for `Device-Independent Text Language', and is an
|
|
ASCII text representation of a DVI file.

DTL Commands
|
|
------------
|
|
|
|
variety <variety-name> Specifies name of DTL file type.
|
|
|
|
Naturally, `variety' has no DVI equivalent.
|
|
|
|
The other DTL commands correspond one-to-one with DVI commands, but I
|
|
have used briefer names (except for `special') than those used in the
|
|
DVI standards document.
