TODO list and thoughts

existing tools:

    cvs_checksum:

    pkg_assignments2pkgpath:

    pkg_cleanup_distdir:

    pkg_cmp_summary:
       - test for -m
       - -f <p> use pkgpath only for comparison
       - -f <n> use pkgbase only for comparison
       - -f <pn> use pkgbase and pkgpath for comparison
       - automatic removal of #-comments

    pkg_grep_summary:

    pkg_list_all_pkgs:

    pkg_micro_src_summary:
       - rewrite it! There is no reason to "emulate" 'make'.
         Sometimes it is enough to run bmake for cut off Makefile.

    pkg_refresh_summary:

    pkg_src_fetch_var:
       - remove it, see pkg_micro_src_summary

    pkg_src_summary:
       - new option for exit code 0 if everything was done successfully,
         1 otherwise

    pkg_summary2bb_pkgs:

    pkg_digger:
       - position-dependent -1|-3|-9

    pkg_digger_backend:

    pkg_summary2deps:

    pkg_summary4view:
       - another format for DEPENDS, BUILD_DEPENDS and CONFLICTS,
         (convertors for RHEL yum, Debian apt, OpenSolaris IPS)

    pkg_uniq_summary:

    pkg_update_src_summary:
       - use "pkg_grep_summary -t strfile PKGPANA"

    pkg_update_summary:
       - reimplement it using 'pkg_grep_summary -S FILE_NAME file'
         and...

    pkg_lint_summary:
         - checks for bad patterns like foobar<=1.1.1nb*
         - improve REQUIRES/PROVIDES checks, i.e. use
           PROVIDES from dependencies only
         - CONFLICTS vs. actual PLISTs in packages
         - distfiles checksums
         - check binaries and their REQUIRES and analyse Makefile

new tools?
    - replacement for lintpkgsrc -m

    - (unsure) additional tool for fields reordering?

    - rfc822_to_summary and (?)debian_to_summary(?) for converting an
      information about Debian packages to pkg_summary(5) format.
      For pkg_online database server for Debian packages?

    - pkg_summary2INDEX
      pkg_summary2PKGDB

    - pkg_op_summary <refresh|intersect|subtract>

ANY IDEAS? LET ME KNOW
