| 50 | Gives print quotes to users. |
---|
| 51 | |
---|
| 52 | command line usage : |
---|
| 53 | |
---|
| 54 | pykotme [options] [files] |
---|
| 55 | |
---|
| 56 | options : |
---|
| 57 | |
---|
| 58 | -v | --version Prints pykotme's version number then exits. |
---|
| 59 | -h | --help Prints this message then exits. |
---|
| 60 | |
---|
| 61 | -P | --printer p Gives a quote for this printer only. Actually p can |
---|
| 62 | use wildcards characters to select only |
---|
| 63 | some printers. The default value is *, meaning |
---|
| 64 | all printers. |
---|
| 65 | |
---|
| 66 | examples : |
---|
| 67 | |
---|
| 68 | $ pykotme --printer apple file1.ps file2.ps |
---|
| 69 | |
---|
| 70 | This will give a print quote to the current user. The quote will show |
---|
| 71 | the price and size of a job consisting in file1.ps and file2.ps |
---|
| 72 | which would be sent to the apple printer. |
---|
| 73 | |
---|
| 74 | $ pykotme |
---|
| 75 | |
---|
| 76 | This will give a quote for a job consisting of what is on standard |
---|
| 77 | input. The quote will list the job size, and the price the job |
---|
| 78 | would cost on each printer. |
