+%description
+In multi-process environments (eg mod_perl, forking daemons, etc), it's
+common to want to cache information, but have that cache shared between
+processes. Many solutions already exist, and may suit your situation
+better:
+
+* *
+
+  the MLDBM::Sync manpage - acts as a database, data is not automatically
+  expired, slow
+
+* *
+
+  the IPC::MM manpage - hash implementation is broken, data is not
+  automatically expired, slow
+
+* *
+
+  the Cache::FileCache manpage - lots of features, slow
+
+* *
+
+  the Cache::SharedMemoryCache manpage - lots of features, VERY slow. Uses
+  IPC::ShareLite which freeze/thaws ALL data at each read/write
+
+* *
+
+  the DBI manpage - use your favourite RDBMS. can perform well, need a DB
+  server running. very global. socket connection latency
+
+* *
+
+  the Cache::Mmap manpage - similar to this module, in pure perl. slows
+  down with larger pages
+
+* *
+
+  the BerkeleyDB manpage - very fast (data ends up mostly in shared memory
+  cache) but acts as a database overall, so data is not automatically
+  expired
+
+In the case I was working on, I needed:
+
+* *
+
+  Automatic expiry and space management
+
+* *
+
+  Very fast access to lots of small items
+
+* *
+
+  The ability to fetch/store many items in one go
+
+Which is why I developed this module. It tries to be quite efficient
+through a number of means:
+
+* *
+
+  Core code is written in C for performance
+
+* *
+
+  It uses multiple pages within a file, and uses Fcntl to only lock a page
+  at a time to reduce contention when multiple processes access the cache.
+
+* *
+
+  It uses a dual level hashing system (hash to find page, then hash within
+  each page to find a slot) to make most 'get()' calls O(1) and fast
+
+* *
+
+  On each 'set()', if there are slots and page space available, only the
+  slot has to be updated and the data written at the end of the used data
+  space. If either runs out, a re-organisation of the page is performed to
+  create new slots/space which is done in an efficient way
+
+The class also supports read-through, and write-back or write-through
+callbacks to access the real data if it's not in the cache, meaning that
+code like this:
+
+  my $Value = $Cache->get($Key);
+  if (!defined $Value) {
+    $Value = $RealDataSource->get($Key);
+    $Cache->set($Key, $Value)
+  }
+
+Isn't required, you instead specify in the constructor:
+
+  Cache::FastMmap->new(
+    ...
+    context => $RealDataSourceHandle,
+    read_cb => sub { $_[0]->get($_[1]) },
+    write_cb => sub { $_[0]->set($_[1], $_[2]) },
+  );
+
+And then:
+
+  my $Value = $Cache->get($Key);
+
+  $Cache->set($Key, $NewValue);
+
+Will just work and will be read/written to the underlying data source as
+needed automatically.
