Robopages is a small footprint rapid-application CMS without graphical or content complexity limitations, geared primarily toward unix-savvy developers. Most Content Management Systems seek to make development easier for non-professionals. Robopages concedes that market and targets professional developers instead. If you are familiar with ssh, scp, bash, sed, perl, php, css and most of all with terminal windows and the keyboard--you can mock up a complex website faster--with Robopages--than with any other system.
I like it!
I wrote it, so it must be good.
