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.
`none'
Don't suppress any warnings.
`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.
