+
+* There Be Dragons Here
+
+This is a very incomplete port of some scsh functionality for Guile
+1.9.x/2.0. I have intentionally not maintained full scsh
+compatibility--it may, however, be a future goal.
+
+* Implementation Goals
+
+** scsh functionality
+
+*** Process Notation
+
+Looks easy, most of it is implemented in syntax-rules.
+
+*** SRE
+
+irregex-guile.scm (instructions within)
+
+Patch sent to irregex <http://synthcode.com/scheme/irregex/> author to
+define a guile module.
+
+*** scsh awk loop
+
+This will be difficult to do well. A naive rewrite based on the docs
+using syntax-case will probably be best initially. The awk
+implementation in scsh does a number of hairy optimizations and is
+written in an explicit-renaming macro system and so any conversion
+will require quite a bit of effort.
+
+*** tty/pty interface
+
+This has slightly more features that the Guile tty/pty interfaces
+AFAICT (I've only looked at the docs so far). Will need to be a fresh
+implementation (no sense in porting the scheme48/scsh C interfaces)
+and probably belongs in Guile itself.
