#called from /usr/local/petget/downloadpkgs.sh and petget.
#passed param is the path and name of the downloaded package.
#/tmp/petget_proc/petget_missing_dbentries-Packages-* has database entries for the set of pkgs being downloaded.
#w456 warning: petget may write to /tmp/petget_proc/petget_missing_dbentries-Packages-alien with missing fields.
#w478, w482 fix for pkg menu categories.
#w482 detect zero-byte pet.specs, fix typo.
#100110 add support for T2 .tar.bz2 binary packages.
#100426 aufs can now write direct to save layer.
#100616 add support for .txz slackware pkgs.
# 20aug10 shinobar: excute pinstall.sh under original LANG environment
#  6sep10 shinobar: warning to install on /mnt/home # 16sep10 remove test code
# 17sep10 shinobar; fix typo was double '|' at reading DESCRIPTION
# 22sep10 shinobar clean up probable old files for precaution
# 22sep10 shinobar: bugfix was not working clean out whiteout files
#110503 change ownership of some files if non-root.
#110523 support for rpm pkgs.
#110705 fix rpm install.
#110817 rcrsn51: fix find syntax, looking for icons. 110821 improve.
#111013 shinobar: aufs direct-write to layer not working, bypass for now.
#111013 revert above. it works for me, except if file already on top -- that is another problem, needs to be addressed.
#111207 improve search for menu icon.
#111229 /usr/local/petget/removepreview.sh when uninstalling a pkg, may have copied a file from sfs-layer to top, check.
#120107 rerwin: need quotes around some paths in case of space chars. remove '--unlink-first' from tar (was introduced 120102, don't think necessary).
#120126 noryb009: fix typo.
#120219 was not properly internationalized (there was no TEXTDOMAIN).
#120523 may need to run gio-query-modules and/or glib-compile-schemas. (refer also rc.update and 3builddistro)
#120628 fix Categories= assignment in .desktop files. see also 2createpackages in woof.
#120818 Categories management improved. pkg db now has category[;subcategory] (see 0setup), xdg enhanced (see /etc/xdg and /usr/share/desktop-directories), and generic icons for all subcategories (see /usr/local/lib/X11/mini-icons).
#120901 .desktop files, get rid of param on end of Exec, ex: Exec=gimp-2.8 %U
#120907 post-install hacks.
#120926 apply translation for .desktop file if langpack installed.
#121015 01micko: alternative code to delete %-param off end of Exec line in .desktop file.
#121109 fixing Categories field in .desktop may fail, as DB_category field may not match that in .desktop file, so leave out that $tPATTERN match in $PUPHIERARCHY.
#121109 menu category was not reported correctly in post-install window.
#121119 change in layout of /etc/xdg/menus/hierarchy caused regex pattern bug.
#121119 if only one .desktop file, first check if a match in /usr/local/petget/categories.dat.
#121120 bugfix of 121119.
#121206 default icon needs .xpm extension. note puppy uses older xdg-utilities, Icon field needs image ext.
#130112 some deb's have a post-install script (ex: some python debs).
#130126 'categories.dat' format changed.
#130219 grep, ignore case.
#130305 rerwin: ensure tmp directory has all permissions after package expansion.
#130314 install arch linux pkgs. run arch linux pkg post-install script.
#131122 support xz compressed pets (see dir2pet, pet2tgz), changed file test
