I'm currently working on updating liblcf and easyrpg-player to v0.7.0 [0,1].
As part of this new release, the liblcf library now bundles some header-only C++ libraries
[2,3].
Those are Boost-licensed, which means the package's effective license changes from
"MIT and BSD" to "MIT and BSD and Boost".
A.FI.
