3.2.1 Use of Escapes

They are used in several places in a2ps:

Page markers

Headers, footers, titles and the water mark (see Headings Options), in general to print the name of file, page number etc. On a new sheet a2ps first draws the water mark, then the content of the first page, then the frame of the first page, (ditto with the others), and finally the sheet header and footers. This order must be taken into account for some escapes (e.g., ‘$l.’, ‘$l^’).

Named output

To specify the generic name of the file to produce, or how to access a printer (see Your Printers).

Delegation

To specify the command associated to a delegation (see Your Delegations).

Table of Content

To specify an index/table of content printed at the end of the job.

Variables in PostScript prologue

To allow the user to change some parameters to your prologues (see Designing PostScript Prologues).
