+SUMMARY="A shell tool for executing jobs in parallel locally or on remote machines"
+DESCRIPTION="GNU parallel is a shell tool for executing jobs in parallel using \
+one or more computers. A job can be a single command or a small script that \
+has to be run for each of the lines in the input. The typical input is \
+a list of files, a list of hosts, a list of users, a list of URLs, or a list \
+of tables. A job can also be a command that reads from a pipe. \
+GNU parallel can then split the input and pipe it into commands in parallel.
+If you use xargs and tee today you will find GNU parallel very easy to use \
+as GNU parallel is written to have the same options as xargs. If you write \
+loops in shell, you will find GNU parallel may be able to replace most of \
+the loops and make them run faster by running several jobs in parallel.
+
+GNU parallel makes sure output from the commands is the same output as you \
+would get had you run the commands sequentially. \
+This makes it possible to use output from GNU parallel as input \
+for other programs.
+
+For each line of input GNU parallel will execute command with the line as \
+arguments. If no command is given, the line of input is executed. \
+Several lines will be run in parallel. GNU parallel can often be used as \
+a substitute for xargs or cat | bash."
