Module Name:    pkgsrc
Committed By:   rillig
Date:           Sun Feb  6 18:00:08 UTC 2022

Modified Files:
        pkgsrc/pkgtools/url2pkg/files: url2pkg.py url2pkg_test.py

Log Message:
url2pkg: extract code for analyzing the distfile URL

In a few commits, this will allow url2pkg to be run from a category
directory, thereby omitting the need to create the package directory
manually.

No functional change.
