End-of-line

NMReDATA tags use backslash ("\") as end-of-line character. This is because some functions of CDK libraries sometimes ignore end-of-line (<EOL>, ASCII code 10); since the NMReDATA format needs a line separator, we introduced the backslash. When reading tags, we have to ignore the usual <EOL> except for Version 1 of the NMReDATA.

Tag should look like this...

>  <NMREDATA_ASSIGNMENT>
A, 48.3010, 1 ;the label "A" corresponds to atom one which is the carbon of the CH2\
B, 20.3220, 2 ;atom two is the carbon of the CH3\
a, 2.6100, H3 ;"H3" refers to the hydrogen atom of atom 3 (the oxygen)\
b, 4.8020, H1 ;"H1" refers to the hydrogen atoms of atom 1 (of the CH2)\
c, 1.4010, H2\

but it may look like this (note how data items 2, 3 and 4 are split across two lines)

>  <NMREDATA_ASSIGNMENT>
A, 48.3010, 1 ;the label "A" corresponds to the atom one which is the carbon of the CH2\
B, 20.3220, 
2 ;atom two is the carbon of the CH3\
a, 2.61
00, H3 ;"H3" refers to the hydrogen atom of atom 3 (the oxygen)\
b, 4.8020, H1 ;"H1" refers to the hydrogen 
atoms of atom 1 (of the CH2)\
c, 1.4010, H2\

Note: There will never be two consecutive <EOL>, because this is the end-of-tag signal.

Conclusion: when reading tags, the <EOL> should be ignored and then the "\" be replaced with <EOL>. When writing, the <EOL> should always come after a backslash.
