   8 mkdeb - Create a Debian package (.deb)
   9
  10 =head1 SYNOPSIS
  11
  12 mkdeb [-m | --multiarch]
  13
  14 =head1 DESCRIPTION
  15
  16 Create a *.deb file according to the package name and version info found in F<./deb/DEBIAN/control> file
  17 and include all file in the package found in F<./deb> folder. Update some of C<control> file's fields, eg.
  18 C<Version> (increase by 1 if there is any file in the package newer than C<control> file), C<Installed-Size>...
  19
  20 In I<multiarch> mode, instead of F<./deb> folder, it takes data from all folders in the current working
  21 directory which name is a valid Debian architecture name (eg. amd64, i386, ...), and stores temporary
  22 files in F<./deb> for building each architecture's package.
  23
  24 Mkdeb also considers C<mkdeb-perms.txt> file in the current working directory to set
  25 some file attributes in the package, otherwise all file attributes are gonna be the same as on the original.
  26 Each line in this file looks like:
  27
  28 <B<MODE>> <B<OWNER>> <B<GROUP>> <B<PATH>>
  29
  30 Where
  31
  32 =over 8
  33
  34 =item <B<MODE>>
  35
  36 is an octal file permission mode, 3 or 4 digits, or "-" to ignore
  37
  38 =item <B<OWNER>>
  39
  40 UID or name of the owner user
  41
  42 =item <B<GROUP>>
  43
  44 GID or name of the owner group
  45
  46 =item <B<PATH>>
  47
  48 the file's path itself to which the attributes are applied, relative to F<./deb> directory.
