See bash man page, section "REDIRECTION / Here Documents":
The format of here-documents is as follows:
<<[-]word
here-document
delimiter
[...]
If any characters in word are
quoted, the delimiter is the result of quote removal on word, and the
lines in the here-document are not expanded. If word is unquoted, all
lines of the here-document are subjected to parameter expansion, com-
mand substitution, and arithmetic expansion.
