Short: desktop front-end to Andrew Brooks' index of RO2/RO3 ProggersManual
PRM_Index is a desktop front-end to Andrew Brooks' index of the RISC-OS 2
and RISC-OS 3 Programmers' Reference Manual.  Simply type in a subject and
the program displays the first sixteen matches it finds, their page numbers
and the volume number.  This version contains a greatly improved RISC OS 3
index.  The index files are plain text and may be used without the user
interface.
