Dump file content into a variable, how to?

[Ismael Valladolid Torres]

A hopefully obvious question from a probably Lisp newbie.

I want my .emacs to dired on launch a given directory. The name of the
directory is stored into a file ~/.removable. So I need to "cat" the
file content into a variable, then maybe do a file-directory-p and
finally dired the directory.

But I don't know how to "cat" a file content into a
variable. shell-command will be no useful as I don't need the "cat"
output in the echo area nor in another buffer, I need it into a
variable.

Any ideas welcome.

Cordially, Ismael
