A Copyright object contains a Header paragraph and a list of additional
Files or License paragraphs. It provides methods to iterate over those
paragraphs, in addition to adding new ones. It also provides a mechanism
for finding the Files paragraph (if any) that matches a particular
filename.
Typical usage::
with io.open('debian/copyright', 'rt', encoding='utf-8') as f:
c = copyright.Copyright(f)
header = c.header
# Header exposes standard fields, e.g.
print('Upstream name: ', header.upstream_name)
lic = header.license
if lic:
print('Overall license: ', lic.synopsis)
# You can also retrieve and set custom fields.
header['My-Special-Field'] = 'Very special'
# Find the license for a given file.
paragraph = c.find_files_paragraph('debian/rules')
if paragraph:
print('License for debian/rules: ', paragraph.license)
# Dump the result, including changes, to another file.
with io.open('debian/copyright.new', 'wt', encoding='utf-8') as f:
c.dump(f=f)
It is possible to build up a Copyright from scratch, by modifying the
header and using add_files_paragraph and add_license_paragraph. See the
associated method docstrings.

dS ) a� Create a new copyright file in the current format.
:param sequence: Sequence of lines, e.g. a list of strings or a
file-like object. If not specified, a blank Copyright object is
initialized.
:param encoding: Encoding to use, in case input is raw byte strings.
It is recommended to use unicode objects everywhere instead, e.g.
by opening files in text mode.
:param strict: Raise if format errors are detected in the data.
Raises:
:class:`NotMachineReadableError` if 'sequence' does not contain a
machine-readable debian/copyright file.
MachineReadableFormatError if 'sequence' is not a valid file.

Technically it can't be a perfect inverse, since format_multline must
replace all-whitespace lines with ' .'. Specifically, this function:
- Does nothing to the first line
- Removes first character (which must be ' ') from each proceeding line.
- Replaces any line that is '.' with an empty line.

Only * and ? wildcards are supported. Literal * and ? may be matched via
\* and \?, respectively. A literal backslash is matched \\. Any other
character after a backslash is forbidden.
Empty globs match nothing.
