      apksigcopier is a tool for copying android APK signatures from a signed APK to an unsigned one (in order to verify reproducible builds).
      It can also be used to compare two APKs with different signatures.
      Its command-line tool offers four operations:

      * copy signatures directly from a signed to an unsigned APK
      * extract signatures from a signed APK to a directory
      * patch previously extracted signatures onto an unsigned APK
      * compare two APKs with different signatures (requires apksigner)
