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