[yocto] Get version information of receipes

[Jens Rehsack]

Hi,

as the author of https://github.com/rehsack/Packager-Utils I think about adding support to generate recipes which would allow me add+update primarily perl modules (more later, baby steps ^^).

Is there an easy way to get dedicated information about a recipe by asking bitbake about it? Original dev-environment is pkgsrc where a
$ make showvars VARNAME="$(LIST_OF_VARS)" shows all the vars in list of request (eg. PKG_VERSION, DISTFILES, MASTER_SITES, ...).

Relevant would be anything which is needed to identify the used upstream object - for many recipes to many indirections and *.inc files would be needed to be parsed (re-implementation of bitbake).

Cheers
