 # @FUNCTION: pypi_sdist_url
-# @USAGE: [<project> [<version> [<suffix>]]]
+# @USAGE: [--no-normalize] [<project> [<version> [<suffix>]]]
 # @DESCRIPTION:
 # Output the URL to PyPI sdist for specified project/version tuple.
 #
-# If <package> is unspecified, it defaults to ${PN}.
+# The `--no-normalize` option disables project name normalization
+# for sdist filename.  This may be necessary when dealing with distfiles
+# generated using build systems that did not follow PEP 625
+# (i.e. the sdist name contains uppercase letters, hyphens or dots).
+#
+# If <package> is unspecified, it defaults to ${PN}.  The package name
+# is normalized according to the specification unless `--no-normalize`
+# is passed.
 #
 # If <version> is unspecified, it defaults to ${PV}.
 #
 # If <format> is unspecified, it defaults to ".tar.gz".  Another valid
 # value is ".zip" (please remember to add a BDEPEND on app-arch/unzip).
