# Monkey patching packaging.markers to handle extras names in a

# case-insensitive manner:
|
|
# pip considers dnspython[DNSSEC] and dnspython[dnssec] to be equal, but
|
|
# packaging markers treat extras in a case-sensitive manner. To solve this
|

# issue, we introduce a comparison operator that compares case-insensitively

# if both sides of the comparison are strings. And then we inject this
