4. Configuration Files

a2ps reads several files before the command line options. In the order, they are:

  1. the system configuration file (usually `/usr/local/etc/a2ps.cfg') unless you have defined the environment variable `A2PS_CONFIG', in which case a2ps reads the file it points to;

  2. the user's home configuration file (`$HOME/.a2ps/a2psrc')

  3. the local file (`./.a2psrc')

Because a2ps needs architecture dependent information (such as the local lpr command) and architecture independent information (such as the type of your printers), users have found useful that `a2ps.cfg' be dedicated to architecture dependent information. A sub configuration file, `a2ps-site.cfg' (see section 4.1 Including Configuration Files) is included from `a2ps.cfg'.

The file `a2ps.cfg' is updated when you update a2ps, while `a2ps-site.cfg' is not, to preserve local definitions.

In the configuration files, empty lines and lines starting with `#' are comments.

The other lines have all the following form:
 
Topic: Arguments

where Topic: is a keyword related to what you are customizing, and Arguments the customization. Arguments may be spread on several lines, provided that the last character of a line to continue is a `\'.

In the following sections, each Topic: is detailed.
