This is because Go libraries (though not programs) are stored as source code in 
the
output directory and later fetched and rebuilt when you build one of their 
dependents.

So, if go-foo requires go-bar requires go-baz, go-bar will be rebuilt whenever 
go-foo
is built. But if go-bar doesn't use propagated-inputs, the go-baz dependency of 
go-bar
will be absent from the build environment.

In this case, we're talking about go-github-com-emersion-go-bcrypt depending on 
the
go-golang-org-x-crypto package; since x-crypto is probably already propagated 
in the
hydroxide build environment, as it's quite a common package, you don't see any 
issues;
but were you to write a package that solely depended on go-bcrypt, it'd fail to 
build
because x-crypto wasn't in the build environment.

IMO, the use of `vCard' as the object of that phrase without any further 
explanation
of what `vCard' is sounds a wee bit strange, so maybe something like:

  parse and format the vCard file format

Assuming vCard is a file format.
