ChmSee — CHM Document Viewer for Linux
Originally at chmsee.gro.clinux.org
ChmSee was a GTK-based viewer for Microsoft Compiled HTML Help files (.chm) on Linux. It lived at chmsee.gro.clinux.org and was the standard CHM reader recommendation in Chinese-language Linux distribution guides for several years.
What it was
Many late-1990s and early-2000s software documentation packages — particularly Chinese-language programming references — shipped exclusively as CHM files. Linux had no first-class native CHM reader at the time. ChmSee filled that gap with a clean GTK interface that handled the proprietary CHM format, supported a navigable contents tree, and rendered the embedded HTML cleanly.
Reception
The 1.0.0 release was widely covered in Chinese-language Linux blogs (LinuxTOY's coverage being a notable example) and translated into reviews on Japanese and Chinese-language Linux software directories. ChmSee remained the recommended CHM viewer in Chinese Linux distribution forums through the 2010s.
Modern alternatives
By the late 2010s, kchmviewer (Qt-based) and xCHM (wxWidgets-based) had become the more actively-maintained options on Linux. CHM as a documentation format itself fell out of common use as documentation moved online and to PDF.
