Strings
=======

[FIXME: this is pasted in from Tom Lord's original guile.texi and should
be reviewed]

For the sake of efficiency, two special kinds of strings are available
in Guile: shared substrings and the misleadingly named "read-only"
strings.  It is not necessary to know about these to program in Guile,
but you are likely to run into one or both of these special string types
eventually, and it will be helpful to know how they work.

String Fun

New functions for manipulating strings.

Shared Substrings

Strings which share memory with each other.

Read Only Strings

Treating certain non-strings as strings.
