How can I capitalize the first letter of each word?

Question

I need a script in any language to capitalize the first letter of every word in a file.

Thanks for all the answers.

Stackoverflow rocks!

Another solution with awk, pretending to be simpler instead of being shorter ;)

$ cat > file

  ^D
$ awk 'function tocapital(str) {
           if(length(str) > 1)
               return toupper(substr(str, 1, 1)) substr(str,2)
           else
               return toupper(str)
       }

       {
           for (i=1;i<=NF;i++) 
               printf("%s%s", tocapital($i), OFS);
           printf ORS
       }
      ' < file
