-# Running
-# =======
-# 
-# Just start `./setup.sh`. It will do the following:
-# 
-# 1. download apt sources and apt-file data for the amd64 Debian sid snapshot at
-#    `20141211T041251Z` and store them in a directory tree rooted at
-#    `./debian-sid-amd64`
-# 2. go through all binary packages which have a file `DEBIAN/triggers` in their
-#    control archive (the list is retrieved from binarycontrol.debian.net)
-#    and for each package:
-#   1. download and unpack its control archive
-#   2. store all interest-await file triggers in the file `interested-file`
-#   3. store all interest-await explicit triggers in the file `interested-explicit`
-#   4. store all activate-await file triggers in the file `activated-file`
-#   5. store all activate-await explicit triggers in the file `activated-explicit`
-#   6. remove the downloaded binary package and unpacked control archive
-# 3. go through `interested-file` and for each line:
-#   1. calculate the dependency closure for the binary package and for
-#      each package in the closure:
-#     1. use `apt-file` to get all files of the package
-#     2. check if the current file trigger matches any file in the package
-#     3. store any hits in the file `result-file`
-# 4. go through `interested-file` and for each line:
-#   1. calculate the dependency closure for the binary package and for
-#      each package in the closure:
-#     1. check if the package activates the current file trigger
-#     2. append any hits to the file `result-file`
-# 5. go through `interested-explicit` and for each line:
-#   1. calculate the dependency closure for the binary package and for
-#      each package in the closure:
-#     1. check if the package activate the current explicit trigger
-#     2. store any hits in the file `result-explicit`
-# 
-# Files
-# =====
-# 
-# interested-file
-# ---------------
-# 
-# Associates binary packages to file triggers they are interested in. The first
-# column is the binary package, the second column is either `interest` or
-# `interest-await` and the last column the path they are interested in.
-# 
-# interested-explicit
-# -------------------
-# 
-# Associates binary packages to explicit triggers they are interested in. The
-# first column is the binary package, the second column is either `interest` or
-# `interest-await` and the last column the name of the explicit trigger they are
-# interested in.
-# 
-# activated-file
-# --------------
-# 
-# Associates binary packages to file triggers they activate. The first column is
-# the binary package, the second column is either `activate` or `activate-await`
-# and the last column the path they activate.
-# 
-# activate-explicit
-# -----------------
-# 
-# Associates binary packages to explicit triggers they activate. The first column
-# is the binary package, the second column is either `activate` or
-# `activate-await` and the last column the explicit trigger they activate.
-# 
-# result-file
-# -----------
-# 
-# Associates binary packages with other binary packages they can form a file
-# trigger cycle with. The first column is the binary package containing the file
-# trigger, the second column is the file trigger, the third column is a binary
-# package providing a path that triggers the binary package in the first column,
-# the fourth column is the triggering path of provided by the binary package in
-# the third column.
-# 
-# result-explicit
-# ---------------
-# 
-# Associates binary packages with other binary packages they can form an explicit
-# trigger cycle with. The first column is the binary package interested in the
-# explicit trigger, the second column is the name of the explicit trigger, the
-# third column is the binary package activating the trigger.
