#!/bin/sh
#called from /usr/local/petget/installpreview.sh
#/tmp/petget_installpreview_pkgname (writen in installpreview.sh) has name of package being
#  previewed prior to installation. ex: abiword-1.2.3
#/tmp/petget/current-repo-triad has the repository that installing from (written in pkgchooser.sh).
#  ex: slackware-12.2-slacky
#  ...full package database file is /root/.packages/Packages-slackware-12.2-slacky
#/tmp/petget_missingpkgs_patterns (written in findmissingpkgs.sh) has a list of missing dependencies, format ex:
#  |kdebase|
#  |kdelibs|
#  |mesa-lib|
#  |qt|
#  ...that is, pkg name-only with vertical-bars on both ends, one name per line.
#/tmp/petget_installed_patterns_all (writen in findmissingpkgs.sh) has a list of already installed
#  packages, both builtin and user-installed. One on each line, exs:
#  |915resolution|
#  |a52dec|
#  |absvolume_puppy|
#  |alsa\-lib|
#  |cyrus\-sasl|
#  ...notice the '-' are backslashed.
#110722 versioning info added to dependencies.
#110723 remove hardcoded path /root/.packages, so can run script in Woof.
#110822 versioning operators can be chained, ex: +linux_kernel&ge2.6.32&lt2.6.33
#111107 01micko: fix for '||' messing things up.
#120203 BK: internationalized.
#120221 jemimah: grep '[a-zA-Z]' so as to find deps with all capitals (ex: SDL).
#120831 npierce, jemimah: findmissingpkgs.sh creates /tmp/petget_missingpkgs_patterns and /tmp/petget_missingpkgs_patterns_with_versioning, need to use latter here.
#       refer: http://www.murga-linux.com/puppy/viewtopic.php?p=648934#648934
#120903 revert 120831, broken.
#120903 improve pkg db selection. fixes for versioned dependencies.
#120905 search 4 levels for dependencies.
#120907 max 11 levels, greatly improved speed. progress display at top of screen.
#121102 Packages-puppy-${DISTRO_FILE_PREFIX}- (or Packages-puppy-${DISTRO_COMPAT_VERSION}-) is now Packages-puppy-${DISTRO_DB_SUBNAME}-. refer /etc/DISTRO_SPECS.
#130511 vercmp failed this test: if vercmp 2.2.1 ge 2.2~2011week36; then echo 'greater'; fi -- have solved this in woof, support debdb2pupdb.bac
