This module deals with caching data. It sets up the paths and implements loaders and savers for tables. Best is to set the following variable. When not set, the usual paths will be checked. Personally I prefer the (users) temporary path.

TEXMFCACHE=$TMP;$TEMP;$TMPDIR;$TEMPDIR;$HOME;$TEXMFVAR;$VARTEXMF;.

Currently we do no locking when we write files. This is no real problem because most caching involves fonts and the chance of them being written at the same time is small. We also need to extend luatools with a recache feature.

Once we found ourselves defining similar cache constructs several times, containers were introduced. Containers are used to collect tables in memory and reuse them when possible based on (unique) hashes (to be provided by the calling function).

Caching to disk is disabled by default. Version numbers are stored in the saved table which makes it possible to change the table structures without bothering about the disk cache.

Examples of usage can be found in the font related code.
