TRIXER creates catalogs of transparent fileindexes. A transparent file index is an exactmirror of a directory, except that each of itsfile is void, thus "taking no space", whileapparently having the same size of its indexedcounterpart so as to describe it fully. This isaccomplished by combining sparse files supportwith fusecompress on-the-fly compressiontechnology. This is useful for many purposes, e.g.creating a catalog of your CD/DVD-ROM library to browse its contents without having to physicallyaccess it. The advantage of this software is thata TRIXER catalog is a plain mountable ext2filesystem, allowing enhanced interoperability with the huge lot of available software to handle the catalog in a number of ways.

Changes:
The predetermined limit on catalog size has been removed. XFS is used instead of ext2: the advantage is total inodability and easier calculation of growing amounts, while the disadvantage is the inability to shrink the filesystem. The preemptively huge image approach was discarded in favor of dynamic growing: the number of inodes needed is grossly guessed at addition time and the catalog is grown as needed. mkindex.sh was cleaned up (moving virtualcopy to a inner function, which also improved performance). trxclean.sh was added to clean the mount database.
