35 | A coefficients Manager for PyKota. |

37 | command line usage : |

38 | |
---|
39 | pykoef [options] cofficient1 coefficient2 ... coefficientN |
---|
40 | |
---|
41 | options : |
---|
42 | |
---|
43 | -v | --version Prints pykoef version number then exits. |
---|
44 | -h | --help Prints this message then exits. |
---|
45 | |
---|
46 | -a | --add Adds coefficients if they don't exist in PyKota's |
---|
47 | database. If they exist, they are modified |
---|
48 | unless -s|--skipexisting is also used. |
---|
49 | |
---|
50 | -d | --delete Deletes coefficients from PyKota's database. |
---|
51 | |
---|
52 | -l | --list List informations about the coefficients. |
---|
53 | |
---|
54 | -P | --printer P Only apply the command to printer P's coefficients. |
---|
55 | P can be a comma separated list of printers' names |
---|
56 | or wildcards. |
---|
57 | |
---|
58 | -s | --skipexisting In combination with the --add option above, tells |
---|
59 | pykoef to not modify existing coefficients. |
---|
60 | |
---|
61 | -V | --value v Sets the coefficients' value to v. This value can |
---|
62 | be any real number, positive or negative. |
---|
63 | |
---|
64 | coefficient1 through coefficientN can contain wildcards if the --add option |
---|
65 | is not set. |
