A port can be established in the following manner.
tex4ht.env file. If no such directive exits,
place the file in the directory of tex4ht.env or the work directory. tex4ht and t4ht.
The simplest setting is probably the one which puts the style files tex4ht.sty and *.4ht, the executable files
tex4ht and t4ht (compiled without assigning values to environment variables), the environment files
tex4ht.env and htfcss.env, and the htf files in a single directory accessible from the work directory. In
such a case, one might need only modify slightly the tex4ht.env file before start working with the
system.
The above files are also available zipped together into a single file.
