8 * termcap a TERMCAP compiler
9 *
10 * The termcap database is an ASCII representation of the data
11 * so people may believe that there is no need for a compiler.
12 * Syntax checks and unification however are a property of compilers.
13 * We check for correct data types, output all entries in a unique
14 * order and recode all strings with the same escape notation.
15 * This is needed in to compare two entries and it makes life easier.
