Website Meta Language (WML)  and Its associated command wmk  are together a free and extensible web designer’s off-line HTML generation toolkit for Unix , distributed under the GNU General Public License (GPL v2). It works as an off-line content management system . It is written in ANSI C and Perl 5, built via a GNU Autoconf based source tree and runs out-of-the-box on all major Unix derivates.
WML consists of a control frontend driving up to nine backends in a sequential pass-oriented filtering scheme. Each backend provides a particular core language. WML adds ships with a set of include files that provide higher-level features.
WML’s nine backends are:
- Pass 1: Source Reading and Include File Expansion (ipp)
- Pass 2: HTML Macro Construct Expansion (mp4h)
- Pass 3: Perl 5 Programming Construct Expansion (eperl)
- Pass 4: M4 Macro Construct Expansion (gm4)
- Pass 5: Diversion Filter (divert)
- Pass 6: Character and String Substitution (asubst)
- Pass 7: HTML Fixup (htmlfix)
- Pass 8: Line Stripping and Output Fixup (htmlstrip)
- Pass 9: Output Splitting and Final Writing (slice)
