What is libapache2-reload-perl
libapache2-reload-perl is:
Apache2::Reload reloads modules that change on the disk.
When Perl pulls a file via “require”, it stores the filename in the global hash %INC. The next time Perl tries to “require” the same file, it sees the file in %INC and does not reload from disk. This module’s handler can be configured to iterate over the modules in %INC and reload those that have changed on disk. It can also monitor only specific modules that have registered themselves with Apache2::Reload. It is possible to trigger the check only when a special touch-file has been modified, minimizing the number of stat() calls per request.
