C November 1998 KDC
C WROTE IT!
C Autumn 1999 SPE, AWA, MDW
C New routines ccp4h_init_lib, ccp4h_html_close, ccp4h_summary_beg,
C ccp4h_summary_end
C
C =========
C libhtml.f
C =========
C
C Link destinations can be of the for "#name" for a link in the same
C document. Any other link will be prepended with $CHTML to link to
C the documentation area
C
C The contents of the environment variable $CCP_PROGRAM_ID is concatenated
c to the end of each link name. This allows multiple runs of a single
C program from a script to be combined in one file without the links
C conflicting.
C
C The environment variable $CCP_SUPPRESS_HTML if set suppresses the output
C of most HTML tags. This is useful for devotees of plain text, and
C especially for the command input section.
C
C ccp4h_init_lib(int ihtml, int isumm) - initialise the routines for
C writing tags (html and summary)
C
C ccp4h_init() - write initial comment to identify file
C
C ccp4h_html_close() - write html close tag
C
C ccp4h_toc_beg() - write starting Contents section tags
C
C ccp4h_toc_ent(char*(*) text, char*(*) dest) - write Contents entry
C text= the link text
C dest= the link destination
C
C ccp4h_toc_end() - write ending Contents section tags
C
C ccp4h_graph_beg(x,y) - write starting JLogGraph applet tag
C x = width of graph in pixels
C y = height of graph in pixels
C both can be zero, then they default to 400,300.
C
C ccp4h_graph_end() - write ending JLogGraph applet tag
C
C ccp4h_summary_beg() - begin summary section
C
C ccp4h_summary_end() - end summary section
C
C ccp4h_pre_beg() - begin preformatted (html <pre> tag)
C
C ccp4h_pre_end() - end preformatted (html <pre> tag)
C
C ccp4h_rule() - rule (html <hr> tag)
C
C ccp4h_link(char*(*) text, char*(*) dest) - link (html <a> tag)
C text= the link text
C dest= the link destination
C if dest is not an anchor name (i.e. begins with '#'), then
C the $CHTML path is prefixed automatically.
C
C ccp4h_link_key(char*(*) text, char*(*) dest) - link to CCP4 documentation
C text= the keyparser keyword
C dest= the link destination filename and anchor,
C the $CHTML path is prefixed automatically.
C Between call memparse(.false.) and the main keyparser processing,
C call this routine with any keywords and links which should be
C linked to the program doc. Then call parsefail() to restart
C syntax checking.... e.g.
C call memoparse(.false)
C call ccp4h_link_key('LABIN ','fft.html#labin')
C call ccp4h_link_key('GRID ','fft.html#grid')
C call ccp4h_link_key('FFTSPGRP','fft.html#fftspgrp')
C call parsefail()
C
C ccp4h_header(char*(*) text, char*(*) name, int level) - header
C text= the link text
