[texworks] Project Management type stuff

[Paul A Norman]

Dear Bruno,

Thank you very much for that overview - I found (am still finding it)
it very helpful.

I think I will end up posting on each of the main distributoins lists
to sort it out on a case by case basis.

The simple question I need to pose is, I think, in two parts,

   a) can packages be accessed by \usepackage{} on relative paths from
the document's directory,
   b) and if yes, are there any required path forms (OS issues).

Paul

MikTeX must similarly involve its own file searching library, which may place different restrictions on file names and a different syntax for path specification.

Some accepted file names with spaces directly as \input{file name}, others required quotes \input{"file name"}, others bluntly rejected spaces. Same with 8-bit characters in file names (Textures accepted it, OzTeX rejected it). Textures accepted to typeset in plain TeX a file with spaces in its name, but OzTeX didn't; both refused to typeset in LaTeX a file with a space in its name, owing to the creation and reading of ancillary files (.aux, etc.).
