---|
16 | /* Modified by santana@imag.fr: */ |
---|
17 | /* 4) Added new options at installation : sheet format (height/width in */ |

---|
33 | /* Modified by tullemans@apolloway.prl.philips.nl */ |
---|

---|
67 | /* suppress this feature. */ |
---|
68 | /* 33) Added filename_footer flag for printing file name at bottom */ |
