1.5. The environment variables

You can modify the behavior of the library by defining an environment variable named `TVOPT'. This variable is a set of strings separated by a space character. Valid strings are:

cyrillic        enable cyrillic character set mapping (Linux and VCS only)
latin           enable latin character set mapping (Linux and VCS only)
noarrow         disable the arrow pointer (FreeBSD only)
nogpm           disables support for the GPM mouse driver (Linux only)
novcs           inhibits the use of VCS to do video output (Linux only)

Examples for the Bourne shell:

export TVOPT=nogpm              does not use GPM
export TVOPT="nogpm novcs"      disables both GPM and VCS
export TVOPT=                   cleans the variable

Examples for the C shell:

setenv TVOPT nogpm              does not use GPM
setenv TVOPT "nogpm novcs"      disables both GPM and VCS
unsetenv TVOPT                  cleans the variable
