    1.19 +# Proxy to the Repology
    1.20 +# Problems:
    1.21 +# 1. Function "latest packaged version" widely used here, and it has no JSON API, but only SVG badge.
    1.22 +# 2. So, all version comparisons can be only visually and not automated.
    1.23 +# 3. When the thousands of badges present on the web page, many of them are broken (maybe server
    1.24 +#    drops requests), while our server displays status icons well.
    1.25 +# 4. Default badges are wide and not customizable.
    1.26 +# Solution:
    1.27 +# 1. Make local cache. Update it on demand, but no more than once a day (Repology cached info
    1.28 +#    on a hourly basis). Use cached values when they are not expired.
    1.29 +# 2. Extract and save version(s) from the SVG badges. Values can be compared in the scripts as well
    1.30 +#    as custom badges may be provided.
