===Using concatenations===

<lang Nim>import strutils

# We use the concatenation operator "&" to assemble the strings.

# This is done at compile time and so the result is a long literal.

===Using a long literal string===

<lang Nim>import strutils

const RevDate = "2021-02-05"

# We use a long string literal starting and ending with '"""'.

# We eliminate the multiple spaces by using "splitWhiteSpace"

# instead of "split".
