CHEM - A Program for Typesetting Chemical Diagrams: User Manual
|
|
by Jon L. Bentley, Lynn W. Jelinski, Brian W. Kernighan
|
|
|
|
Historically, this paper was available at
|
|
<http://cm.bell-labs.com/cm/cs/cstr/122.ps.gz>.
|
|
|
|
Many of the examples had to be fixed. Unfortunately, the AWK version of
|
|
chem version does not run on many of these files. The Perl
|
|
version of chem distributed with groff does.
|
|
|
|
Most examples do not use a modern style of depiction. They show carbon
|
|
atoms explicitly, whereas contemporary practice omits all C atoms and
|
|
their bound hydrogen atoms. [A chemist should fact-check this. --GBR]
|
|
|
|
The examples are named and sorted by the section whence they are found
|
|
in CSTR #122. For example, the file 'ch4c_colon.chem' [sic] means an
|
|
example in section 4; the 'c' indicates that it is the third example in
|
|
this section; the name 'colon' is used to describe the content of the
|
|
example.
|
|
|
|
Render the examples with "groff -j".
