software download gives you a fully functional piece of software,
working for a limited period of time. I want users make good
use of Spectragryph, as free of restrictions as possible.

infrequent users might take years before running into it.
Spekwin32 and Spectragryph have been polished in countless
hours day and night. Found bugs are usually fixed in a short

Many features are based on user feedback and users' proposals.
All users are treated equal. To non-commercial users, Spectragryph
is free and will ever be.
