The advantage of Acme is that there isn't much learning: all the commands
are obvious (eg Put writes back to disk), but you do have to learn the mouse
clicks to execute them.

I use sed's language constantly, and look forward to expanding my bag of
tricks with sam.  Stream editors are without-a-doubt the most useful tool I
have for editing files, because I can write scripts that edit them for me.

I found that sam had a limiting command-line interface, so I wrote a script
around it (ssam) that gives at a more sed-like stream-editing interface: -e
accepts a (series of) sam commands; -f accepts the name of a file with sam
commands; and you can pipe in the text you want to change, then use -e or -f
to supply the commands.  It puts all the text it changes on standard output.
 It's in code-review right now, so if you use it let me know (-G sends a
gripe with mail) if it doesn't work well for you.
