(Default is 60). 59 60 =item B<-i=>I<regex>, B<--ignore=>I<regex> 61 62 When processing the list of files and directories, the regular 63 expression specified by this option will be used to indicate those which 64 should not be considered (e.g. backup files, VCS metadata). 65 66 =item B<-r>, B<--recursive> 67 68 Specify that the contents of directories should be added 69 recursively. 70 71 =item B<-c=>I<regex>, B<--check=>I<regex> 72 73 Specify a pattern against which filenames will be matched in order to 74 decide which files to check the license of. 75 76 The default includes common source files. 77 78 =item B<--copyright> 79 80 Also display copyright text found within the file 81 82 =item B<-m>, B<--machine> 83 84 Display the information in a machine readable way, i.e. in the form 85 <file><tab><license>[<tab><copyright>] so that it can be easily sorted 86 and/or filtered, e.g. with the B<awk> and B<sort> commands. 87 Note that using the B<--verbose> option will kill the readability. 88 89 =item B<--no-conf>, B<--noconf> 90 91 Do not read any configuration files. This can only be used as the first 92 option given on the command-line. 93 94 =back 95 96 =head1 CONFIGURATION VARIABLES 97 98 The two configuration files F</etc/devscripts.conf> and 99 F<~/.devscripts> are sourced by a shell in that order to set 100 configuration variables. Command line options can be used to override 101 configuration file settings. Environment variable settings are 102 ignored for this purpose. The currently recognised variables are: 103 104 =over 4 105 106 =item B<LICENSECHECK_VERBOSE> 107 108 If this is set to I<yes>, then it is the same as the B<--verbose> command 109 line parameter being used. The default is I<no>. 110 111 =item B<LICENSECHECK_PARSELINES> 112 113 If this is set to a positive number then the specified number of lines 114 at the start of each file will be read whilst attempting to determine 115 the license(s) in use. This is equivalent to the B<--lines> command line 116 option. 117 118 =back 119 120 =head1 LICENSE 121 122 This code is copyright by Adam D.
