In the latest TDS specs, scripts now reside under the ../scripts path instead of under package entries (like ../context).

One way to locate a script used to be to call kpsewhich with the format "other text files" but now the format is "texmfscripts".

The consequence of this is, that (combined with moved enc and map files in combination with strict paths in the texmf.cnf files), TeX distributions are not downward compatible. The assumption is more or less that users reinstall the whole lot and don't have their own fonts and such -)

Another change is the flattening of format suffixes to fmt (so make sure that you remove the efmt ones when you update binaries); although the spec suggests the usage of an $engine subpath (in order to distinguish formats) it looks like distributions will not implement this (too difficult).

The way context deals with that is the following:

Alternatively, one can (manually) adapt the texmf.cnf file (or have a partial copy in your local tree) that extends the enc + map paths to the old locations

Launching a script, can be done indirectly, using texmfstart, like

texmfstart texexec.pl ... args ...

or one can make a small stub, for instance:

texmfstart --make texexec.pl

and move the resulting bat file in one of your bin path. The texmfstart route is supposed to work with the old and new trees and future trees (since I will try to keep texmfstart downward compatible).

On UNIX, it's hard to distinguish files by type, i.e. texexec can be a stub, perl script, binary, whatever; in this case, texmfstart will create a link(? end of line was missing)

Note that distributions have different means of locating scripts and resources, in which case you depend on the integrety of a distribution. In case of problems, you can always replace the stubs by texmfstart based stubs.

Because of testing for TeXlive (which is the reference cross platform TeX distribution), I package the ZIPs in the new structure, and this means that users who have old trees and binaries may run into problems when they mix things.

[These changes in the enc/map file locations may give users who have their own font trees some headaches; also, if you use scripts in your own scripting tools e.g. in server apps, then you should be aware of the fact that locating scripts needs patches, i.e. the format fed to kpsewhich; Here I have so many scripts that I don't put them all in the path, for instance because of name clashes, and I used to use kpsewhich to locate them; using texmfstart in such cases is more future safe, and with the coming new kpse run-as-deamon libraries it may become faster as well.]

Updating fonts

then run:

textools  --update new e:\tex\texmf

and see what gets reported; if you feel comfortable, run

textools  --update new e:\tex\texmf --merge --force --delete

and then

mktexlsr
