-% tangle.ch for C compilation with web2c.
-%
-% 10/9/82 (HT) Original version
-% 11/29 (HT) New version, with conversion to lowercase handled properly
-% Also, new control sequence:
-% @=...text...@> Put ...text... verbatim on a line
-% by itself in the Pascal output.
-% (argument must fit on one line)
-% This control sequence facilitates putting #include "gcons.h"
-% (for example) in files meant for the pc compiler.
-% Also, changed command line usage, so that the absence of a
-% change file implies no change file, rather than one with the
-% same name as the web file, with .ch at the end.
-% 1/15/83 (HT) Changed to work with version 1.2, which incorporates the
-% above change (though unbundling the output line breaking),
-% so mainly had to remove stuff.
-% 2/17 (HT) Fixed bug that caused 0-9 in identifiers to be converted to
-% Q-Y on output.
-% 3/18 (HT) Brought up to work with Version 1.5. Added -r command line
-% flag to cause a .rpl file to be written with all the lines
-% of the .web file that were replaced because of the .ch file
-% (useful for comparing with previous .rpl files, to see if a
-% change file will still work with a new version of a .web file)
-% Also, made it write a newline just before exit.
-% 4/12 (PC) Merged with Pavel's version, including adding a call to exit()
-% at the end depending upon the value of history.
-% 4/16 (PC) Brought up to date with version 1.5 released April, 1983.
-% 6/28 (HWT) Brought up to date with version 1.7 released June, 1983.
-% With new change file format, the -r option is now unnecessary.
-% 7/17 (HWT) Brought up to date with version 2.0 released July, 1983.
-% 12/18/83 (ETM) Brought up to date with version 2.5 released November, 1983.
-% 11/07/84 (ETM) Brought up to date with version 2.6.
-% 12/15/85 (ETM) Brought up to date with version 2.8.
-% 03/07/88 (ETM) Converted for use with WEB2C
-% 01/02/89 (PAM) Cosmetic upgrade to version 2.9
-% 11/30/89 (KB) Version 4.
