| 37 % for a program to generate a reference. | |

| 2333 | 39 % You only have to set the total width and height of the paper, the |
| 40 % horizontal and vertical margin space measured from *paper edge* | |
| 41 % and the interline and interspec spacing. | |
| 42 % In order to support a new papersize, you have to fiddle with the | |
| 43 % latter four dimensions. Just try out a few values. | |
| 44 % All other values will be computed at process time so it should be | |
| 45 % quite easy to support different paper sizes - only four values to | |
| 46 % guess :-) | |
| 47 % | |
| 48 % To find the configuration places, just search for the string | |
| 49 % "User configuration". | |

| 53 % NOTE ON INTENTIONAL OMISSIONS: This reference card includes many | |
| 54 % Octave commands, but due to space constraints there are some things | |
| 55 % I chose to omit. In general, not all synonyms for commands are | |
| 56 % covered, nor all variations of a command. | |
