- Process input with equations, saving the output for future typesetting with groff to PostScript:
|
|
|
|
|
|
|
|
|
|
`eqn {{path/to/input.eqn}} > {{path/to/output.roff}}`
|
|
|
|
|
|
|
|
|
|
- Typeset an input file with equations to PDF using the [me] macro package:
|
|
|
|
|
|
|
|
|
|
`eqn -T {{pdf}} {{path/to/input.eqn}} | groff -{{me}} -T {{pdf}} > {{path/to/output.pdf}}`
