TCM can be configured by means of a configuration file.
The file $TCM_HOME/lib/tcm.conf is the system-wide
configuration file. It may be overridden by a user's private
configuration file in $HOME/.tcmrc.
The configuration file consists of a number of sections
which start with a keyword identifying the section and then
a {. The section ends by a }.
Sections are separated by white space (one or more spaces, tabs
or newlines). Within a section there are a number of attribute-value
pairs separated by white space and also enclosed by curly braces
(basically it is the same format as the TCM file format in
appendix B).
Comments in the file start with a hash (#). The text
in the same line after the hash is ignored. The section names and
the attributes are case sensitive.
In the file itself you find comment text which gives directions
for what the attributes mean and what attribute values
are possible.
