Combine GNU B<parallel> with another program into a single executable.
Let us say you have developed I<myprg> which takes a single
argument. You do not want to parallelize it yourself.
You could write a wrapper that uses GNU B<parallel> called B<myparprg>:
#!/bin/sh
parallel myprg ::: "$@"
But for others to use this, they need to install: GNU B<parallel>,
B<myprg>, and B<myparprg>.
It would be easier to install if all could be packed into a single
executable.
If B<myprg> is written in shell, you can use B<--embed>.
If B<myprg> is a binary you can use B<--combineexec>.
Here we use B<gzip> as example:
parallel --combineexec pargzip gzip -9 :::
You can now do:
./pargzip foo bar baz
If you want to pass options to B<gzip> you can do:
parallel --combineexec pargzip gzip
Followed by:
./pargzip -1 ::: foo bar baz

=item B<--compress>
Compress temporary files.
