on debian based systems a bash script to take the diff of two packages which is useful for finding what depencies are needed more than a certain metapackage
I have cases where a package is part of lubuntu-core on ubuntu but not part of example running ./depnedsdiff.sh lubuntu-desktop pcmanfm doesn't say that pcmanfm is also a dependency and should already be installed because pcmanfm depends on lubuntu core. Not sure --recursive works well here for depends.
For example if you have tihs over LXLE at least 12.04.4 The distro maintainers thought metapackages would be a bad idea as you should do a fresh install as you customized it but I am using metapackages here. I don't know how all other respins affect metapackages.
If the second argument of the bash script $2 is a dependency of $1 in the script or the metapackage I should check for this. An example of this would be on ubuntu entering ./dependsdiff lubuntu-core pcmanfm which will return pcmanfm dependencies not listed in the depends of lubuntu-core.
I think I should check for $2 with a regular expression on the first metapackage.
