# Program: slacktrack
# Purpose: Tracking & building packages for Slackware v9.1+
#          Inspired by Patrick Volkerding's 'bp' script
#
#          This DOES NOT USE libsentry nor installwatch!
#          This WILL INSTALL THE PACKAGE ON THE SYSTEM (and updates the
#          /var/log/packages database so that you may remove the newly built package).
#
#         * DO NOT USE THIS ON ANYTHING BUT A PACKAGE BUILDING DEVELOPMENT MACHINE *
#
#          You MUST consult the FAQ before using this script so that you avoid
#          including unrelated files in your packages.

# It's in egrep's pattern format.  Note that when this string is used in altertrack
# (as it used to be called), we prefix everything with ^ meaning to only remove the
# listed value if it is at the start of a line.  Eg, /var/log/monkey.log would be removed
# from the list (because /var/log is listed below), but /usr/monkey/var/log/monkey.log
# would not.

# The list of files/directories to exclude from the pre and post-file system scan.
# Note that this is applied to the search itself, unlike EXCLUDE_LIST, which
# means a) if you know what to exclude can make the install a lot faster and
# b) it uses find's -regex syntax.
# Paths are relative to ROOTDIR - if you amend these using the --no-fs-search operator
# you will need to omit the '/' prefix as you can see below:

# Default touch list:
# (ideally there shouldn't be any directories called /install as these are part of the
#  package that are used during installation, and wiped afterwards; but occasionally
#  there is some residue due to a problematic package or a failed build):

                                'root:bin'.  If you use the --setrootowner option then it will
                                reset the directory permissions to root:root
 -f,  --chown-bfiles-root-bin   Set ownerships of files contained within the standard Slackware

                                By default, slacktrack will choose one in /var/tmp
 -L,  --nologhardlinks          Do not log the existence of hard links
 -O,  --chmod-og-w              Run 'chmod -R og-w' over the package directory
 -x,  --exclude '/foo|/bar'     Supply replacement egrep pattern for dir/file exclusion
 -o,  --no-fs-search 'foo\|bar' Supply replacement find regex pattern for pre and post-build file
                                system scans. If you know where the package will install, this can
                                significantly reduce the processing time. Paths are relative to --rootdir
                                [default: mnt\|sys\|proc\|tmp\|home\|lib/udev/devices]

                                its output to the slacktrack log file.
                                Use this for any post build processing scripts that require manual
                                intervention or use a curses interface (for example a 'dialog' script).
      --run-after-withlog <cmd> Run command/script after build script finishes, appending any output
                                to the slacktrack log file.
 -X,  --delete-overlapping      Remove any files from the resulting package's contents that overlap
                                with any of the system's existing installed packages
      --allow-overlapping       Permit the package to contain any files that overlap with existing
                                installed packages [this is the default]
 -Q,  --standard                Select options required to build a compliant Slackware package
      --showdeps                List the installed packages on which this new package depend
      --rootdir                 Change the directory that slacktrack considers to be the root
                                [default: /]
      --touch-filesystem-first  Touch files on the filesystem before scanning filesystem
                                contents
      --touch-filesystem-faster Touch files on the filesystem before scanning filesystem
                                contents, using a faster but less safe method
                                than --touch-filesystem-first
                                This option is _not_ recommended.
 -Y,  --delete-orphaned-pyc     Delete orphaned Python compiled *.pyc files from the package.
