\DOC string_of_file
\TYPE {string_of_file : string -> string}
\SYNOPSIS
Read file and convert content into a string.
\DESCRIBE
When given a filename, the function {strings_of_file} attempts to open the file
for input, and if this is successful reads and closes it, returning the
contents as a single string.
\FAILURE
Fails if the file cannot be opened (e.g. it does not exist, or the permissions
are wrong).
\EXAMPLE
If the file {/tmp/greeting} contains the text
{
Hello world
Goodbye world
}
\noindent then
{
# string_of_file "/tmp/greeting";;
val it : string = "Hello world\nGoodbye world"
}
\SEEALSO
file_of_string, strings_of_file.
