Kpathsea: A library for path searching
4.4 Suppressing warnings
Kpathsea provides a way to suppress selected usually-harmless warnings;
this is useful at large sites where most users are not administrators,
and thus the warnings are merely a source of confusion, not a help. To
do this, you set the environment variable or configuration file value
TEX_HUSH to a colon-separated list of values. Here are the
possibilities:
- `all'
-
Suppress everything possible.
- `checksum'
-
Suppress mismatched font checksum warnings.
- `lostchar'
-
Suppress warnings when a character is missing from a font that a DVI or
VF file tries to typeset.
- `readable'
-
Suppress warnings about attempts to access a file whose permissions
render it unreadable.
- `special'
-
Suppresses warnings about an unimplemented or unparsable
`\special' command.
`tex-hush.c' defines the function that checks the
variable value. Each driver implements its own checks where
appropriate.
