Version 0.63.0, by Aleksey Cheusov, Mon, 13 Jan 2014 18:23:17 +0300

  pkg_grep_summary:
    - almost all search strategies were reimplemented in C for better
      performance, as a result all utilities using pkg_grep_summary(1)
      work much faster.  Strategies still implemented in AWK: awk, kw.
    - converted to use shell's getopts.
    - new regression tests.

  pkg_src_summary:
    - if -m, -d, -D aren't applied, temporary files are not created.
    - adapted for recent paexec(1) improvements.

  pkg_update_src_summary:
    - progress counter is output if -v is applied.

  pkg_summary2deps:
    - workaround for buggy patterns like >=foo-1.* was implemented.

  pkg_summary-utils build infrastructure is completely reimplemented. Now
  it is a two-level project.  Subprojects: scripts and grep_summary
  (enabled by default), doc and tests.

  PKG_TOOLS_BIN env. variable is used at build time as a default
  directory for pkg_info(8) (for OpenBSD/FreeBSD in order to avoid
  conflicts with their native pkg_* tools).

  A number of stupid workarounds for stupid Solaris' userlevel.

  All scripts written in shell uses @SH@ in shebang and therefore uses
  pkgsrc's ${SH} at run time.
