### Description

dpkg.cfg is a simple list of options, the same ones as the command line options, with or without a value.

The tree is a list of either comments or option/value pairs by name. Use “set” to set an option with a value, and “clear” for a bare option.

### Usage Example

>     $ augtool -n
>     augtool> ls /files/etc/dpkg/dpkg.cfg
>     #comment[1] = dpkg configuration file
>     #comment[2] = This file can contain default options for dpkg.  All command-line
>     #comment[3] = options are allowed.  Values can be specified by putting them after
>     #comment[4] = the option, separated by whitespace and/or an `=' sign.
>     #comment[5] = Do not enable debsig-verify by default; since the distribution is not using
>     #comment[6] = embedded signatures, debsig-verify would reject all packages.
>     no-debsig = (none)
>     #comment[7] = Log status changes and actions to a file.
>     log = /var/log/dpkg.log
>     augtool> get /files/etc/dpkg/dpkg.cfg/no-debsig
>     /files/etc/dpkg/dpkg.cfg/no-debsig (none)
>     augtool> get /files/etc/dpkg/dpkg.cfg/log
>     /files/etc/dpkg/dpkg.cfg/log = /var/log/dpkg.log
>     augtool> clear /files/etc/dpkg/dpkg.cfg/testopt
>     augtool> set /files/etc/dpkg/dpkg.cfg/testopt2 test
>     augtool> save
>     Saved 1 file(s)
>     augtool>
>     $ cat /etc/dpkg/dpkg.cfg.augnew

### Augeas Lenses

### record

> let record = [ key keyword . (sep_spc . store word)? . eol ]

Keyword, followed by optional whitespace and value, followed by EOL.

The actual file specification doesn’t require EOL, but the likelihood of the file not having one is pretty slim, and this way things we add have EOL.

### lns

> let lns = ( empty | comment | record ) *

Any number of empty lines, comments, and records.

> let record = [ key keyword . (sep_spc . store word)? . eol ]

Keyword, followed by optional whitespace and value, followed by EOL.

> let lns = ( empty | comment | record ) *

Any number of empty lines, comments, and records.
