  NAME
      dr_symlinks - maintain a symlink forest

  SYNOPSIS
      dr_symlinks

  DESCRIPTION
      For each pair directory/subdirectory under each word in DR_SL_TARGETS, a directory and symlink DR_SL_SOURCE/directory/symlink is created (or
      adjusted).  The script is implemented as a wrapper around oggsymlinks, by Wessel Dankers.

  EXAMPLE
      If, in the configuration file $HOME/.draai/symlinksrc, DR_SL_SOURCE is set to /srv/audio and DR_SL_TARGETS is set to "../data/a  ../data/b",
      while directories

       /srv/data/a/And_You_Will_Know_Us_By_the_Trail_of_Dead/Source_Tags_And_Codes/
       /srv/data/a/And_You_Will_Know_Us_By_the_Trail_of_Dead/The_Century_of_Self/
       /srv/data/a/John_Coltrane/A_Love_Supreme/
       /srv/data/b/John_Coltrane/Giant_Steps/
       /srv/data/b/Tinariwen/Amassakoul/

      exist, the following directories holding the following symlinks will get created in /srv/audio/ :

       And_You_Will_Know_Us_By_the_Trail_of_Dead/Source_Tags_And_Codes ->
	../../../a/And_You_Will_Know_Us_By_the_Trail_of_Dead/Source_Tags_And_Codes/
       And_You_Will_Know_Us_By_the_Trail_of_Dead/The_Century_of_Self ->
	../../../a/And_You_Will_Know_Us_By_the_Trail_of_Dead/The_Century_of_Self/
       John_Coltrane/A_Love_Supreme -> ../../../a/John_Coltrane/A_Love_Supreme/
       John_Coltrane/Giant_Steps -> ../../../b/John_Coltrane/Giant_Steps/
       Tinariwen/Amassakoul -> ../../../b/Tinariwen/Amassakoul/

      All dangling symlinks and empty directories (if any) under /srv/audio/ will get removed. This script is idempotent.

  ANOTHER EXAMPLE
      joostvb@hille:~% ls media/usb/audio/200504/Al_Green
      The_Very_Best_Of/

      joostvb@hille:~% ls media/usb/audio/

      joostvb@hille:~% cat .draai/symlinksrc.usb

      DR_SL_SOURCE=~/media/audio
      DR_SL_TARGETS="$( cd $DR_SL_SOURCE && ls -d ../usb/audio/* )"

      joostvb@hille:~% DR_SL_RCFILE=.draai/symlinksrc.usb dr_symlinks

      joostvb@hille:~% ls -l media/audio/Al_Green
      total 0
      lrwxrwxrwx 1 joostvb joostvb 48 2011-03-11 09:12 The_Very_Best_Of -> ../../usb/audio/200504/Al_Green/The_Very_Best_Of/

  ENVIRONMENT
      dr_symlinks honors booleans: DR_SL_VERBOSE, DR_DEBUG and DR_DRYRUN and strings: DR_SL_RCFILE, DR_SL_TARGETS and DR_SL_SOURCE.

  FILES, CONFIGURATION
      All configuration variables (see ENVIRONMENT) can be set in ~/.draai/symlinksrc. This rc-file is sourced as a shell script.  If DR_SL_RCFILE
      is set, its value is assumed to be the dr_symlinks rc-file.

NAME

       lr_check_service - check existence of Lire service

SYNOPSIS

       lr_check_service service

       lr_check_service -l

DESCRIPTION

       lr_check_service checks if service service is supported in Lire, i.e. if there is a DLF converter registered under that name.

       When called with the -l (for `list') option, lr_check_service lists all registered DLF converters.

       Like all Lire scripts, you might want to call this script via lr_run(1), to deal sanely with this scripts' debug- and logging output.

       You might prefer the lr_log2report(1) --help options to list available services: this command creates a more human-friendly format of the
       list.

EXAMPLE

       Call this script in shell scripts as

	LR_SERVICE="$1"

	LR_SERVICE=`lr_check_service "$LR_SERVICE" || true`
	if test -z "$LR_SERVICE"
	then
	   echo >&2 "$tag err lr_check_service failed"
	   exit 1
	fi

	# now go using $LR_SERVICE

       .
