Checksums-Sha1

The Checksums-Sha1 field can appear in a control file with the checksums of source files. This is used in the Debian environment which verifies the source of each project before compiling it and generating an official Debian package.

wpkg may make use of those fields once it supports source packages. Until then they are ignored.

Debian defines the first line of the field as "must be empty", although there is certainly no reason for such, we also verify that this is the case to be as compatible as possible.

The format of one line is:

<checksum> <file size in byte> <filename>
