[ale] HOW2->automate search/replace text in ALL *.c files in Tree?

[Christopher]

There's a program called streplace (it can be found on ebiblio) that has a
recursive function.  It's a command line program that could easily be called from
any shell script.  It complements grep, sed and awk nicely.

The syntax is similar to:   streplace "stringa" "stringb" filename [-R]


Cheers,
