There is use-cases where a command's standard input should be filled
with a file's content. In order to stay consistent with the names of the
other fields, `stdin` is now the field which accepts such a path.
`stdin_str` has been created in order to also support the use of a raw
string.
Sometimes, you want hooks to use different parameters depending on the
certificate. In order to achieve this, it is now now possible to
configure environment variables at certificate scope.
Thanks to this, the default hooks have been rewrote in order to use
cover more use cases.
If someone used the example the way it was defined, file-access issues
may arise. This new example add two new hooks to fix it. The example
should now work in most environment although the path may need to be
adapted.
Documentation is a crucial point for every project, and the most
effective and traditional way to document a program is to write man
page. Here, the mdoc is used because it is simple.
Because the documentation is quite different from the project itself,
the man pages and others helpful files are distributed under a different
license. For this usage, the GNU All-Permissive License is adequate.
