My point is that sed (or any external command) should not be used to chop a single string, even if it means several instructions where a single regex and an external program would have done the job. You can execute many shell statements in the time it takes to call an external command.
In a pipeline, where multiline input is coming from other commands, and not from the echoing of a single string, sed is fine.

makeastheme
MAKEASTHEME(1x) MAKEASTHEME(1x)
NAME
makeastheme, installastheme - manage themes in the Afterstep windows manager.
SYNOPSIS
makeastheme [--theme <theme_name>] [--no_wharf] [--no_pager] [--no_winlist] [--no_background]
installastheme [--theme <theme_name>] [--no_wharf] [--no_pager] [--no_winlist] [--no_background]
DESCRIPTION
This bundle of two Perl scripts is used to implement themes in the AfterStep window manager for X (http://www.afterstep.org).
At this time, these scripts are becoming solid beta quality. I would still highly recommend you to backup your configuration files in the
~/.afterstep dir. The easiest way to undo a theme is to simply restore your old files.
This theme pack currently supports the following modules and options:
Wharf: Pager:
BgColor Align
Pixmap Back
TextureColor BalloonBack
TextureType BalloonBorderColor
BalloonBorderWidth
WinList: BalloonFore
Font DesktopImage
Fore Font
Back Hilight
Justify Image
Pixmap (AS 1.5b6 pl2) SmallFont
Of course, the look file and desktop background is supported. Also, any images specified in the look file or the module options above are
also carried with the theme that is built.
This theme pack expects to find the ~/.afterstep/desktop/themes directory. Each theme should be a subdirectory from there. When you down-
load a theme, untar it in the themes dir. Also, when you build a theme, if you want to bundle any unique icons for use in the database
file, put them in the specific subir of the themes dir.
Also, the theme pack will only look in ~/.afterstep for module configuration files. That means when building a theme, it only takes modi-
fications from that dir. If the config files aren't there, makeastheme will ignore that module. When installing a theme, installastheme
will only edit files in ~/.afterstep. If it doesn't find any modules there, it will skip that module. At a minimum, you should have
'wharf', 'pager', and 'winlist' files in the ~/.afterstep dir.
OPTIONS
Both installastheme and makeastheme take the same command line, which can be in any order. The directory from which the scripts are called
is irrelevant. All directory paths are coded into the scripts and double-checked at runtime. After running installastheme, you will need
to manually restart AfterStep for the changes to take place.
When making the themes, you simply run makeastheme with the --theme <theme_name> argument and any of the other command line arguments you
might want to use. This script will grab all the config files necessary and all images specified within those config files. It then cre-
ates the theme in your '~/.afterstep/desktop/themes'
--theme
this option is used to specify the theme to install. With installastheme it is mandatory. With makeastheme if unspecified, the
$USER environmental variable will be used instead.
--no_wharf, --no_pager, --no_winlist, --no_background
Each of these options tell the scripts to skip processing for each of these modules. For makeastheme it is similar to saying, "I
don't have anything interesting in this module, don't store those options in the theme." For installastheme it is similar to say-
ing, "I really like my <module>, don't change any settings in there."
