Please add your own entries at the bottom of this file. If possible,
include the name of an example package where a warning should occur.

* warn about the use of ${WRKDIR:=...}, as this construct should only
  be used with lists.
* Of the user-defined variables, some may be used at load-time and some
  don't. Find out how pkglint can distinguish them.
* Make sure that no variable is modified at load-time after it has been
  used once. This should at least flag BUILD_DEFS in bsd.pkg.mk.
* ${MACHINE_ARCH}-${LOWER_OPSYS}elf in PLISTs etc. is a NetBSD config.guess
  problem ==> use of ${APPEND_ELF}
* Packages including lang/python/extension.mk must follow the Python version
  scheme. Enforcing PYPKGPREFIX for those is most likely a good idea.
* Check for parallel files/dirs whose names differ only in case.
* If a dependency depends on an option (in options.mk), it should also
  depend on the same option in the buildlink3.mk file.
* Complain about ${PKGSRC_COMPILER} == "sunpro", which should be
  !empty(PKGSRC_COMPILER:Msunpro).
* don't complain about "procedure calls", like for pkg-build-options in
  the various buildlink3.mk files.
* if package A conflicts with B, then B should also conflict with A.
* When pkglint runs on a case-insensitive filesystem, it should still
  point out problems that only occur on case-sensitive filesystems. For
  example, devel/p5-Net-LDAP and devel/p5-Net-ldap should be considered
  different paths.
* Warn about using REPLACE_PYTHON without including application.mk.
