relic - RE-LICense a given file, set of files, or directory of files
from the Mozilla source tree
Usage:
relic [options...] [files...]
relic [options...] < files...
Options to Select Mode (use one):
<none> List the licenses in each file.
-s, --statistics Should a summary table of licenses in each file.
The -x, --extended option may be added to show
some additional detail to the stats.
-r, --relicense Modify the given files to include to
appropriate Mozilla license, where
"appropriate" is either the NPL/GPL/LPGL
tri-license if was already under the NPL or
the MPL/LPGL/GPL license in all other cases.
-R, --force-relicense
Relicenses files (as -r|--relicense), but
does NOT skip files that already appear to
have a complete license.
-A, --add Add a license to files that do not appear to
have one.
-I, --initial-developers
Display initial developer for each file (-s is
suggested).
General Options:
-h, --help dump this help and exit
-V, --version dump this script's version and exit
-v, --verbose verbose output
-d, --debug more verbose output
-f, --force Continue processing after an error. (Errors
are summarized at end.)
-q, --quick Quick scanning. Use only basic license checks
(only use in report mode).
-M, --MPL Replace NPL licenses with MPL ones.
-a, --all Check all files (only skip CVS directories).
--dry-run Go through motions but don't actually change
any files.
--backup Make backups of changes files with
relicensing. Backup filenames are the
original filename suffixed with a ~# where
"#" is the lowest number to avoid a file
conflict.
-o <orig_code_is> Provide fallback value for the "Original
Code is" block.
-D <orig_code_date> Provide fallback value for the date
that is part of the "Original Code is" block.
-i <initial_dev> Provide fallback value for the "Initial
Developer of the Original Code is" block.
-y <year> Provide fallback value for "Initial
Developer" copyright year.
--defaults Use the following default fallback values:
original_code_is: "mozilla.org Code"
initial_copyright_date: "2001"
initial_developer: "Netscape Communications
Corporation"
Note: the "Original Code" date is generally
not required, so a default is not included
here.
Examples:
# List license in files under mozilla/js/src.
relic mozilla/js/src # list licenses in files
relic -s mozilla/js/src # show summary stats on licenses
relic -r mozilla/js/src # re-license files
