|
|
|
|
|
|
|
|
85
|
|
|
|
|
|
|
Note: In this document, Sanskrit words are transliterated using the ITRANS |
86
|
|
|
|
|
|
|
scheme. |
87
|
|
|
|
|
|
|
|
88
|
|
|
|
|
|
|
These functions and constants were not included directly in |
89
|
|
|
|
|
|
|
L as they are more useful stand-alone. None of |
90
|
|
|
|
|
|
|
them are exported by default. |
91
|
|
|
|
|
|
|
|
92
|
|
|
|
|
|
|
Most of the functions operate on L objects which I would like to |
93
|
|
|
|
|
|
|
change wherever possible. |
