-#
-# Short overview
-#
-# We expect to find (1) a directive file, specifying the directory to
-# store into (syntax details later); (2) the actual file to be
-# distributed (no signature); (3) a detached signature for (2).
-#
-# For instance:
-#   foo-1.2.tar.gz.directive.asc, signed (gpg --clearsign) ASCII text
-#                                 about what to do with the other two files.
-#   foo-1.2.tar.gz, the file to upload (could be anything) with no sig.
-#   foo-1.2.tar.gz.sig, detached binary signature (gpg -b) for uploaded file.
-#
-# The directive file must always contain a 'directory', 'version' and
-# 'filename' directive, unless when run in compatibility mode ($V1_COMPAT_MODE
-# is set), in which case directive files with only a 'directory' directive are
-# allowed.
-#
-# Alternatively, we expect to find only a directive file. This file must have
-# a name that ends in 'directive.asc', and must contain one or more of these
-# directives: 'symlink', 'rmsymlink' and 'archive', in addition to the obligatory
-# 'directory' and 'version' directives. A 'filename' directive is not allowed.
-#
-# A 'comment' directive is always allowed.
-#
-# Permissions of directives are controlled on a per package basis. For each
-# package, one or more seperate GPG public keyrings are maintained. All signed
-# files that are part of a triplet must be signed by a permitted key for the
-# specific package named in the directive file. Each package is only allowed
-# write access to its own directory (with the same name as the package) within
-# the public ftp hierarchy. Write access to subdirectories of that directory is
-# allowed. Limiting write access to specific directories on a per package basis
-# minimizes the impact from the compromise of a maintainer's GPG private key. The
-# public keyrings form a hierarchy where keys in superdirectories can apply to
-# files uploaded to subdirectories. Example:
-#
-#   Jim can only upload to aspell/dict/en so his key is located in
-#   packages/aspell/dict/en/pubring.gpg. Paul can upload to any aspell
-#   directory so his key is in packages/aspell/pubring.gpg. When Paul
-#   uploads a file to aspell/dict/en it looks for his key in
-#   packages/aspell/dict/en/pubring.gpg first, then finds it in
-#   packages/aspell/pubring.gpg.
-#
-# Package config files are:
-#   1. $package_config_base/$package_name/pubring.gpg
-#        GNUPG public keyring. For a given package, the directive
-#        file and file to be uploaded, must be signed with a key from
-#        the package's keyring.
-#        If a file is to be uploaded into a subdirectory of the package
-#        directory, the subdirectory in the package config directory will
-#        be checked for a pubring.gpg first, going up to the parent directory
-#        until a match is found.
-#   2. $package_config_base/$package_name/email
-#        Email addresses that are sent mail when uploads succeed or
-#        fail for a given package.  One email address per line.
-#
-# This is written for use with ftp instead of as a cgi script because we
-# don't want to run an httpd on ftp.gnu.org.  In general, it tries to do
-# the minimum possible.
-#
-# We execute gpgv, lsof, mkdir, mv, pwd and tar.  Executions are such that
-# it's not possible for the shell to be invoked.  We make use of Perl
-# module Net::SMTP to send email.
